Swagger API documentation

Our staging system provides Swagger / OpenAPI documentation of our HTTP REST API.

The swagger docs are correct by construction (compiled from the server code), and they are complete up to bots/services and event notification payloads (as of 2023-01-16).

There are several ways to interpret this kind of documentation:

  • Read it as a reference

  • Generate client code from it

  • Interactively explore the API by making requests

Swagger docs (Swagger 2.0)

The Swagger / OpenAPI 2.0 documentation for endpoints depends on the API version. For a list of all swagger docs for all supported API versions, visit https://staging-nginz-https.zinfra.io/api/swagger-ui.

To learn which versions are supported, look at https://<nginz-host>/api-version. (See also.)

If you want to get the raw json for the swagger (ie., for compiling it into client code in typescript, kotlin, swift, …), replace swagger-ui with swagger.json in the above URL pattern.

Example: doing it manually

To get the versions a backend (staging-nginz-https.zinfra.io in this case) supports, execute:

curl https://<nginz-host>/api-version

The URL to open in your browser for the development version 4 is https://<nginz-host>/v4/api/swagger-ui/.

On-prem and test instances, versioning

The above is valid for the official wire.com staging environment and includes both all released API versions and the current development version, which changes continuously until released.

If you talk to any other backend, the development version may differ. Try to ask the backend you’re talking if it exposes its docs itself:

curl https://nginz-https.<custom-staging>.example.com/<version>/api/swagger-ui/
curl https://nginz-https.<custom-staging>.example.com/<version>/api/swagger.json

Internal endpoints

Swagger docs for internal endpoints are served per service. I.e. there’s one for brig, one for cannon, etc.. This is because Swagger doesn’t play well with multiple actions having the same combination of HTTP method and URL path.

Internal APIs are not under version control.

The URL pattern is similar to that of public endpoints for latest version: https://<nginz-host>/api-internal/swagger-ui/<service>.

If you want to get the raw json of the swagger: https://<nginz-host>/api-internal/swagger-ui/<service>-swagger.json.

Federation API

Finding the source code for an end-point

A route internal ID is provided for every end-point. See Named, and internal route IDs in swagger for details and usage.
