# APIkit Compatibility

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

APIkit modules support Mule 4. Review protocol and language coverage in the tables on this page when
you plan AsyncAPI, gRPC, GraphQL, OData, REST, or SOAP APIs. For APIkit versions that align with
[FIPS 140-2](https://docs.mulesoft.com/mule-runtime/latest/fips-140-2-compliance-support) expectations, see
[APIkit Release Notes](https://docs.mulesoft.com/apikit/latest/apikit-release-notes).

## APIkit for SOAP Module Versions and Mule Runtime

APIkit for SOAP 1.7.0 provides broad Mule runtime compatibility. APIkit for SOAP 2.0.0 is the major
successor to 1.6.10 and requires JDK 17 and Mule runtime 4.9.11 or later. APIkit for SOAP 1.6.5
through 1.6.10 are deprecated.
