Summary

Getting invalid_format error when trying to send raw data in REST adapter OIC.

Content

Hi all,

The rest API expects to send data in below format

Body

raw (application/x-www-form-urlencoded)

C0004 1001 AT020 1102 BK 12111 6/30/2014 41235.2567896789

Example RequestIngestion API - Bank Balances

curl --request PUT \
--url 'https://{datacenter}.api.bl.corp/dataingestion/accounts/bank-balances?message-version=4'; \ --header 'Authorization: Bearer d5f32012337d5dc69ef64a320225f56e' \
--header 'Cache-Control: no cache' \
--header 'Content-Type: application/x-www-form-urlencoded'

How should the request in REST be modeled to send data in this format. Tried multiple combinations in OIC REST Request didnn't work. Any input will be helpful.
