The Azure APIM doesn't import Container App OpenAPI Specification

IlicMarko 25

I have been attempting to have APIM import our API which resides on Azure Container Apps service. The Container App service has an open API specification on the endpoint /openapi but when the API is imported to APIM the operations are not being created as expected. The operations have been wildcarded rather than created based on the specification.

I would like to have it automatically, rather than change it every time manually.

IlicMarko Thanks for posting your question in Microsoft Q&A. Can you share more info about the difference after import vs Open API specification. Is it possible to share the OpenAPI specification?

When I import Container App APIM generates wildcard operations instead of Open API Specification which is already included in Container App. Open API specification is as follows:

{"openapi":"3.0.1","info":{"title":"Custom API title","version":"3.14"},"servers":[{"url":"https://calculatorswagger.ambitioussand-d37b45d1.westeurope.azurecontainerapps.io","description":"Generated server url"}],"paths":{"/calculateCashLoan":{"post":{"tags":["financial-controler"],"operationId":"getTestData","requestBody":{"content":{"application/json":{"schema":{"type":"string"}}},"required":true},"responses":{"200":{"description":"OK","content":{"*/*":{"schema":{"type":"string"}}}}}}}},"components":{}}

IlicMarko thanks for sharing the Open API spec. I imported the API using this spec and found it generated only one POST operation for getTestData as described in the spec (see screenshot below:).

If you are able to reproduce this issue, we might need to review your APIM instance and investigate the backend logs. Please send an email to azcommunity@microsoft.com referencing this thread with your subscription ID (not name), details and subject as "Attn: Muthu". I will assist you with next steps.

IlicMarko Thanks for sharing the additional details.

Update for the community:

Initially, the container app was imported in APIM via Open API Spec as .yaml file and it generated wild card operations (doc reference: OpenAPI specification versus wildcard operations). IlicMarko resolved the issue by changing the spec to .json and worked perfectly.
