Quick answer
An asset tracking API connects location data to your ERP and WMS by tying each update to an asset, shipment, or workflow record. GPX, an AI-powered asset tracking platform, provides a REST API, an SDK, and signed webhooks. Your integration rules decide which events update business records and which go to review first.
Your equipment reaches the jobsite, and dispatch still calls to confirm it. A returnable container arrives at the plant, and finance and receiving work from different records. Salesforce’s 2026 Connectivity Benchmark found that enterprise app counts grew from 897 to 957 in a year, and only 27% of those apps are integrated.
Connecting those systems also creates security exposure. The 2023 edition of the OWASP API Security Top 10 names ten risk categories, including broken authentication, broken object level authorization, and unrestricted resource consumption. A useful integration needs trustworthy updates, controlled access, and clear rules for changing business records.
What is an asset tracking API?
An asset tracking API is a software interface that lets another application request or exchange tracking records. It ties physical movement to the asset, shipment, and inventory records your operation already keeps.
The GPX platform provides a REST API and SDK to create shipments and pull their history. Signed webhooks carry JSON payloads for route deviation, dwell exceeded, delivered, and other documented events. Your integration translates each record into the workflow the receiving system understands.
Keep responsibility clear across the connection:
| Component | Primary responsibility | Business use |
|---|---|---|
| Tracking platform | Provide asset observations and tracking events | Locate equipment, containers, and shipments |
| Integration service | Match identifiers, validate records, and apply rules | Turn observations into controlled updates |
| ERP | Maintain enterprise asset and financial records | Connect location context with ownership and cost |
| WMS | Maintain warehouse inventory and execution records | Support receiving and movement verification |
How does asset tracking software integrate with an ERP system?
Integration starts with shared identity. Link each tracker to the ERP asset, container, or shipment record it represents. Keep that link current when hardware moves to a new asset or a shipment closes.
ISA-95 defines electronic information exchange between enterprise and manufacturing control systems, starting with the interface between levels 3 and 4. Its stated goal is to reduce the risk, cost, and errors of building those interfaces. The lesson for your project: agree on what each system owns before you connect them.
- Define the decision. Pick one action, such as flagging equipment at the wrong site or confirming a container reached its destination.
- Map the identifiers. Link tracker IDs to asset records, shipment references, and site codes. Name the owner who corrects unmatched records.
- Set update rules. Separate informational observations from authorized business changes. Require extra confirmation wherever a financial or inventory consequence follows.
- Test exceptions. Replay duplicate, delayed, missing, and out-of-order records. Confirm that rejected updates stay visible to the team that resolves them.
What data flows from a GPS or BLE tracker into an ERP system?
The tracker sends observations through the tracking platform. Your integration matches location, observation time, device identity, and event context to your enterprise records. Confirm the exact fields in the vendor’s documentation before you build the mapping.
A GPS fix describes a position. A BLE observation depends on the tracker or gateway that detected the tag and where that reader sits. GPX AssetTag Pro tags report through a GPX tracker or gateway in range, and BLE RoadWired turns forklifts and vehicles into mobile BLE gateways. Keep that distinction in your data instead of treating every observation as an equally precise position.
A container tracking API also needs a reliable link between each container and its current shipment. Purchase orders, ownership, and accounting classifications stay under the authority of your business systems.
Does asset tracking software work with SAP, Oracle, or other ERP systems?
GPX lists SAP and Oracle among its ERP connections, along with TMS, WMS, and data warehouses. It also posts alerts to Microsoft Teams channels and connects through Zapier for no-code workflows. That platform-agnostic approach runs through GPX’s enterprise asset tracking software.
Confirm your specific workflow before you buy. Ask which objects are supported, which direction data travels, and who maintains the connection. A named ERP integration does not mean every custom transaction is already configured.
What is the difference between an API and a webhook for asset or location data?
An API request starts when your application asks for data or submits an operation. A webhook starts when the tracking service pushes an event notification to your receiving application.
Use API requests to retrieve history, check current records, and reconcile gaps. Use webhooks to trigger workflows around specific events. GPX sends signed webhooks for route deviation, dwell exceeded, and delivered.
A third pattern is the polled feed. Your application asks for everything new since its last request, using a token that marks its place. That is a pull model, not an unsolicited push like a webhook.
Plan for both fast notification and later reconciliation. Store incoming events before you process them, log successful updates, and make replay safe. Use idempotency keys so receiving the same webhook event twice never creates a duplicate ERP transaction.
Can asset tracking data feed into a warehouse management system?
Yes. Tracking data feeds a WMS through an integration that matches observed assets to inventory, container, or shipment records. The payoff is fewer manual checks between physical arrival and system confirmation.
Separate arrival from receipt. A tracker reaching a site does not confirm the shipment quantity, item condition, or completed receiving checks. Your WMS keeps authority over the inventory transaction.
For example, an arrival observation triggers a receiving task when your process requires inspection. The completed task then authorizes the inventory update. Our guide to warehouse management systems explains the execution role behind those decisions.
For shared event meaning, GS1 EPCIS defines visibility event data covering the what, where, when, why, and how of products and assets, within one company and across trading partners. Use it as a reference for event semantics. It does not imply GPX implements a particular EPCIS interface.
Why location updates still leave teams chasing assets
The first failure is identity. A tracker stays assigned to a container after someone moves it to another load, so dispatch sees a current position on the wrong shipment. Receiving then burns hours reconciling records that each look valid.
A documented reassignment process stops that mismatch before it spreads into downstream systems.
The next failure is time. An older observation arrives after a newer one, or a connection resumes and sends stored history. If the integration treats arrival order as movement order, the asset appears to move backward.
Store observation time separately from receipt time. Then define exactly how older records affect current status.
Coverage gaps add a volume problem. A tracker that buffers observations while out of cellular range sends them as a batch when it reconnects, and a yard full of trackers reconnecting at once floods the integration. Queue incoming records and throttle writes so the surge stays inside your ERP’s API rate limits.
Reporting frequency forces a trade-off. Business teams ask for constant updates, but every extra report from a battery-powered tracker shortens its service life. Set reporting intervals by the decision each asset supports, and rely on event webhooks for exceptions instead of polling the API on a tight schedule.
Field mappings drift over time. An ERP upgrade, such as a move to SAP S/4HANA or Oracle Cloud, changes objects and custom fields, and the integration starts rejecting records or writing them to the wrong place. Version your mappings and retest them with every ERP release.
The last failure is ownership. Operations expects IT to fix unmatched assets, IT expects the site to fix them, and finance trusts a status nobody reviewed. Assign an owner to each exception type and keep unresolved updates visible. Reliable integration needs a correction process as much as a data connection.
How do you evaluate an asset tracking vendor’s API and webhook security before buying?
Ask for documentation and a technical review with the people who will run the connection. Separate the vendor’s verified capabilities from the controls your own integration must supply.
- Authentication and permissions. Confirm how applications authenticate and how access is limited to authorized assets, sites, and records. Get the API authentication method in writing.
- Webhook verification. GPX signs each webhook with HMAC-SHA256 and sends the signature in an X-GPX-Signature header. Request the secret-management process and delivery behavior before you build the receiver.
- Input validation. Validate incoming fields, identifiers, and permitted values before anything writes to your ERP or WMS.
- Failure handling. Set retry, replay, logging, and reconciliation procedures. Ask for documented rate limits and availability terms instead of assuming them.
- Endpoint controls. Review how webhook destinations are registered, approved, and changed. Restrict which resources your integration components contact.
OWASP’s 2023 API Security Top 10 lists webhooks among the concepts that make server side request forgery more common. The risk appears when a system fetches a resource from a URL another party supplies. Review outbound requests anywhere your integration accepts a configurable URL.
The same 2023 OWASP list also warns against trusting third-party API data without validation. Its guidance: assess the provider’s API security posture, require TLS, validate and sanitize received data, and never blindly follow redirects. Apply those checks even to providers you know well.
What is MCP, and why does it matter for AI agents querying asset data?
MCP stands for Model Context Protocol. GPX offers an MCP server so your own AI agents, including Copilot, ChatGPT, and Claude, query live shipment, container, and asset context directly.
That opens a faster route to operational answers. A manager asks where a container is or which shipments need attention. The agent queries live context instead of waiting for someone to export a report.
Scout AI, GPX’s built-in analyst, answers plain-language questions over location and IoT data, such as “Which assets have been idle for more than 48 hours?” It applies role-based access to every answer. Modern logistics teams treat tracking as an intelligence layer, not a status page.
Keep query access separate from authority to change business records. GPX’s MCP server gives agents access to live context. It does not grant unrestricted ERP writes or autonomous approval of inventory and financial transactions.
When GPX Is Not the Right Fit
GPX serves enterprise operations and businesses tracking 10 or more high-value assets. A single tracker for a family car or a pet belongs with our consumer and SMB sister brand, Logistimatics.
GPX is not a dashcam, a telematics suite, an ERP, or a WMS. Buy it for asset and supply-chain visibility connected to the systems you already run. Purchasing, accounting, and warehouse execution stay with the applications built for those jobs.
Start With One Workflow Your Team Has to Trust
Choose an asset tracking API around the transaction your team needs to trust. Require proof that the right asset reaches the right record, exceptions stay visible, and replay leaves business data consistent.
Get that foundation right and the next step follows. AI-powered visibility puts agents to work answering questions and flagging exceptions inside the workflows your teams already use.
Bring your ERP or WMS owner, sample records, and one specific workflow to the conversation. Talk to the GPX team about connecting tracking events to the systems your operation already runs.
Frequently Asked Questions (FAQs)
Does a delivered event replace proof of delivery?
No. A tracking event and proof of delivery serve different purposes. GPX sends a delivered webhook, but that event is not a signed receipt or a completed inspection. Define the evidence your business requires before you close the delivery record.
Should every location update change ERP inventory?
No. Most location observations belong in tracking history or an exception queue. Change inventory only when the observation satisfies your receiving rules and required approvals.
What should an integration pilot measure?
Measure whether records match correctly, updates reach the intended workflow, and exceptions reach the responsible team. Test duplicates, delayed observations, and interrupted delivery. Count the time operators spend correcting records when you judge the result.
How does GPX sign its webhooks?
GPX signs each webhook with HMAC-SHA256 and sends the signature in an X-GPX-Signature header. Your receiver recomputes the signature and rejects any payload that fails the check. Verify first, then store the event so you can replay it safely.
