Motivation and Context

How did you test it?

1. Create merchant account (get default profile_id)
2. Create api key
3. Use update endpoint of business profile to pass config.

curl --location 'http://localhost:8080/account/merchant_1716883344/business_profile/pro_5PdcjX4zYfC8X2PFjCel' \
--header 'Content-Type: application/json' \
--header 'Accept: application/json' \
--header 'api-key: test_admin' \
--data '{
    "extended_card_info_config": {
        "ttl_in_secs": 300,
        "public_key": "pub_key"
    }
}'

4. Retrieve the business profile and the config should be returned in the response

curl --location 'http://localhost:8080/account/merchant_1716883344/business_profile/pro_5PdcjX4zYfC8X2PFjCel' \
--header 'Content-Type: application/json' \
--header 'Accept: application/json' \
--header 'api-key: test_admin' \
--data ''
