— Posting SIAM Messages in MBS —
In order for OAuth2 to work in MBS, messages posted through SIAM queues (psp.in.siam.client.*) from ServiceNow must contain the @EndpointUrlPath attribute (specified in the outbound Table Map). Below is a sample SIAM message posted to a SIAM queue:
{“topic”:”siam”,”type”:”common_request”,”key”:”dev12381″,”name”:”common_request.insert”,”attributes”:”EndpointUrlPath=/serviceRequests,cipher=3,customer=support/testuser,Number=RITM9414370…”,”extra”:””,”psp_timestamp”:”2019-10-24 16:17:02″,”value”:”{VALUE}”}
Next comes specifying the Access Key & Secret Token in the PSP SIAM Endpoint record [psp_siam_endpoint]. We should create one similar to the one attached.
As shown, every parameter must be prefixed with auth_field_ so they’re interpreted correctly by MBS.
