Hello @Aruna N,
Welcome to the Microsoft Q&A Platform! Thank you for asking your question here.
To update the API URLs in Azure API Management after migrating from Apigee:
First update API URL in APIM, go to the APIs section in APIM and edit the API URL to reflect the new endpoint from Azure.
Then update policies in inbound, outbound, or on-error policies, update the set-backend-service base URL with the new API URL.
<inbound>
<set-backend-service base-url="https://new-api.azure.com" />
</inbound>
After implementing the above steps use APIM's Test tool to verify the new API URL is working and Update client applications to use the new API URL.
Also, for your reference please follow this DOCUMENT regarding the API policies and how to implement step by step.
