> For the full documentation index, see: https://docs.mulesoft.com/llms.txt

Configuration properties for API Gateway Runtime changed in Mule 4.

These properties have to be defined in the `wrapper.conf` for Mule 3 to work as API Gateway:

```text
-M-Danypoint.platform.client_id=clientId
-M-Danypoint.platform.client_secret=clientSecret
-M-Danypoint.platform.platform_base_uri=https://anypoint.mulesoft.com/apiplatform
-M-Danypoint.platform.coreservice_base_uri=https://anypoint.mulesoft.com/accounts
-M-Danypoint.platform.contracts_base_uri=https://anypoint.mulesoft.com/apigateway/ccs
-M-Danypoint.platform.analytics_base_uri=https://analytics-ingest.anypoint.mulesoft.com
```

Starting from Mule 4, these properties have to be defined in the `wrapper.conf` in order to work as
an API Gateway:

```text
-M-Danypoint.platform.client_id=clientId
-M-Danypoint.platform.client_secret=clientSecret
-M-Danypoint.platform.base_uri=https://anypoint.mulesoft.com
-M-Danypoint.platform.analytics_base_uri=https://analytics-ingest.anypoint.mulesoft.com
