Credit Card Transaction failed > Merchant e-Solutions: Invalid Profile ID or Key

Verify if the Profile ID and Key are entered correctly. This needs to be checked on the Merchant e-Solutions Credit Card setup under Setup > Accounting > Payment Processing Profile using an administrator role.

You can do the following steps:

1. Go to Setup> Accounting> Payment Processing Profile
2. Click edit on the Merchant e-Solutions setup
3. Copy-paste the profile id and key sent by Merchant e-Solutions.
4. Payer Authentication = False
5. Test Mode = False
6. Inactive = False
7. Enable all gateway request types
8. Click on save.

If the same issue is not resolved still, you need to contact Merchant eSolutions to verify the correct profile key and id.
