API & DATA FLOW

Every API integration that crosses your boundary, on one map.

Mapnostics traces who calls your API, which endpoints they hit, and the third-party services you call back out to — read from your code. A call to your own endpoint is drawn as an arrow into that endpoint, and a runtime-built URL is flagged as unproven.

API Flow

Inbound and outbound integrations, and the data crossing each boundary

An arrow means one component calls another. It does not mean one runs first. A call to our own endpoint is drawn as an arrow into that endpoint, not as a service.

An API flow map traced from your code

✓

Inbound and outbound in one view

API clients, your routes, your modules and the external services — the whole boundary, not just the half you were looking for.

✓

Honest about what it can't prove

A URL built at runtime cannot be resolved statically, so it is drawn with a dashed rule and labelled, never asserted as fact.

✓

An arrow is a call, not an order

The diagram shows which component calls which — it does not claim one runs first, so you read dependency, not sequence.

Common questions

What does API Flow map?

Every integration crossing your boundary: who calls your API and which endpoints they hit, and the third-party services your code calls back out to.

How does it handle a dynamically built URL?

A call whose target URL is constructed at runtime is flagged as unproven rather than shown as a confirmed integration.

Is API Flow traced from the code or from live traffic?

From the code — the import and call graph — not from runtime logs or network traffic.
