Seemingly after updating CiviCRM to 5.50.3 and webform_civicrm to 7.x-5.8 on drupal 7.83, webform payments fail. Watchdog says

The CiviCRM "contribution transact" API returned the error: "Unknown api version" 
when called by function "validate" on line 97 of wf_crm_webform_postprocess.inc 
with parameters: "Array ( [credit_card_type] => MasterCard [credit_card_number] => xxxxxxxxxx...[snip]
[form_token] => qnqM4nlUWJSVIPZiCsb57jdigsIZ76jGiG0Aa9a6nyc [form_id] => 
webform_client_form_2556 [op] => Submit [payment_instrument_id] => 1 [payment_processor] 
=> 5 [card_type_id] => 2 [pan_truncation] => 7947 [check_permissions] => [version] => 3 )

As a result, it appears everything to be handled after payment is not done, storing the payment in civicrm, sending mails/invoices, adding contacts to groups, etc - however, strangely, the payment seems to have been done.

Assuming this string "Unknown api version" comes from Civi/API/Request.php, https://lab.civicrm.org/dev/core/-/blob/fb87724ca7f9fd42560e0729e9e46a3c...

it seems $params['version'] is not 3 or 4.

It is clear in the error message version is either 3 or '3' - I can't see where the value comes from in function contributionParams - if it comes from a post, it might be a string?

Do you have https://civicrm.org/extensions/contribution-transact-api installed? You need that now if using webform with contributions.

  • Thanks os much ! How could I have known ?! yes, that changes the error. I am testing on a development server, and not sure if all my settings are right. it now keeps telling me It appears that this transaction is a duplicate even when using different amounts. Do you know if there is anything else I need to configure to have wf_civicrm work with the contribution-transact-api ?
