Multiple APIM APIs to the same Function App

Question

I have a function app available at:

https://contoso.azurewebsites.net/api/MyFunction

When I link the function to api management it defaults to this:

https://contoso-apim.azure-api.net/MyFunction

The function takes a handful of query strings. I'd like to add multiple apis to my api managment like this:

https://contoso-apim.azure-api.net/abc goes to https://contoso.azurewebsites.net/api/MyFunction?options=abc
https://contoso-apim.azure-api.net/xyz goes to https://contoso.azurewebsites.net/api/MyFunction?options=xyz

Is this something I can do? It seems trivial but I can't work it out.

@David Thank you for reaching out to Microsoft Q&A. Based on my understanding, you would like to add multiple APIs in APIM which points to the same azure function with different query parameters.

• Use API URL suffix to add multiple APIs like abc, xyz when importing azure function

• Navigate to API, Operations and change URL in Frontend from /MyFunction to / (my function name is HttpTrigger)

• Use rewrite-uri policy in your inbound section to transform template to suit your needs. Refer docs: Rewrite URL and samples for more info.

<rewrite-uri template="MyFunction?options=xyz" />
