BPP: Validation of request payload

[sudhirrg]

Hi all, my team is implementing the BPP and BAP spec for Mobility.
I have questions about the validation by the Protocol Server.
The Protocol Server validates each request per the Beckn Network’s Open API schema.
(1) Does the Protocol Server check for well-formedness of the request only, or does it also validate the existence of required (mandatory) elements per the schema definition?
E.g. the Beckn Mobility API definition expects the Intent object passed in the message to contain a fulfillment.start.location. Will the Protocol Server check for the presence of this element in the message?
(2) Does the BPP implementation need to check for the optional fields in the schema?
E.g. to implement search as a BPP, our implementation expects an Intent object containing both a fulfillment.start.location and a fulfillment.end.location.
Will be glad to receive your answers to our questions.

Hello @sudhirrg , Please find my comments below
(1) Does the Protocol Server check for well-formedness of the request only, or does it also validate the existence of required (mandatory) elements per the schema definition?

• protocol server does the following validations

1. for the context object, it checks for schema (well-formedness) , mandatory fields, data types (incase if the field is populated) as per schema
2. for message object, it only checks for the schema (well-formedness) and data types (incase if the field is populated).
3. it validates if the request / response header is present and is signed.

Does the BPP implementation need to check for the optional fields in the schema?

• Its always better if BPP does the necessary validations of the request object to ensure that the required fields are populated which is required to process the request and return appropriate responses.

if you can share the sample beckn request / response with us, we will review the same and will update if any corrections are required.

I have attached sample Beckn requests and responses, as you asked. Could you go over them and suggest changes or corrections? Thanks in advance!
