We created custom policy templates:  GetRequestHeaders, SetPortRestriction, SetResponseHeaders to be added as a policy template. When developer uses PAPI to deploy new API get the following error: 

{"error": {
"code": "ValidationException",
"message": {
"lang": "en",
"value": "The request could not be completed due to data input errors."
},
"detail": {
"errorCode": "483",
"devErrorMessage": "The request could not be completed due to data input errors.",
"userErrorMessage": "The request could not be completed due to data input errors.",
"userErrorKey": "error.validation.entity",
"validationErrors": [
{
"field": "ApiEula",
"error": "API Eula referenced doesn't exist.",
"key": "error.apiApiEulaNotExists"
},
{
"field": "PolicyTemplateArguments",
"error": "Cannot save Portal Published API with mismatch of Policy Template arguments compared to Gateway Policy Template.",
"key": "error.api.gateway.policytemplate.arg.mismatch"
}
]
}
}}

Problem facing was related to the endpoint POSTING to
/tenantname/Apis
This reference is for the 1.0 version which did not support multiple templates 

The current endpoint is:
/tenantname//2.0/Apis
Supports multiple policy templates also has different format for payload 
 

Portal 4.2

[INSTRUCTION]
=============
Step 1 Create custom policy template 

• Created Policy add logic for service getRequestHeaders
• Set as Portal Publisher Fragment 
• Create Encapsulated Assertion

Step 2 Check that the Policy Template is available in the Portal review API look under “Proxy Configuration”
 

• Access Portal Tenant: https://tenant4.support.local/admin/
• Click “Portal API” this will take you to Admin Portal (example: https://apim.support.local/admin)
• API Pull down select “Portal API (tenant4)
• Portal API (Tenant4) click “ApisAulas: API Enf usericenseAgreement operation”
• Click GET /ApiEulas, then submit (Take down the UUID)

• Access Portal Tenant: https://tenant4.support.local/admin/
• Click “Portal API” this will take you to Admin Portal (example: https://apim.support.local/admin)
• API Pull down select “Portal API (tenant4)
• Portal API (Tenant4) click “Apis: API operations”

Step 5: To build the payload for multiple/custom policy temples need to do a get on /2.0/Apis NOT /Apis (this is old with different structure) to understand json structure

NOTE: there is no swagger for Get /2.0/Apis need to use a tool like Postman

• Custom getRequestHeaders
• Quota by Month
