CiviCRM Community Forums (archive)

From my read of the API and docs, I expected that we'd be able to use chained API calls over the HTTP interface (extern/rest.php). I spent a while with this yesterday and didn't see any way to make it function, eventually concluding that it doesn't seem to work yet.

Here's some sample code I'd expect to work (from api/v3/examples/Contact/ChainTwoWebsites.php)

I was testing this against a 4.3 site and haven't had a chance yet to confirm for 4.4. I see that api/api.php has been rewritten a fair bit in 4.5. Would be interested if any other devs who use the extern/rest.php interface can confirm this as a bug for 4.4 or 4.5 branches.

#!/usr/bin/php
<?php

// Use class.api.php from CiviCRM
include('/path/to/site/sites/all/modules/civicrm/api/class.api.php');
$api_params = array(
  'server' => 'http://civicrm.local',
  'api_key' => 'USERKEY',
  'key' => 'SITEKEY',
);

$api = new civicrm_api3($api_params);

$params = array(
  'first_name' => 'abc3',
  'last_name' => 'xyz3',
  'contact_type' => 'Individual',
  'email' => 'man3@yahoo.com',
  'api.contribution.create' => array(
      'receive_date' => '2010-01-01',
      'total_amount' => '100',
      'financial_type_id' => 1,
      'payment_instrument_id' => 1,
      'non_deductible_amount' => '10',
      'fee_amount' => '50',
      'net_amount' => '90',
      'trxn_id' => 15345,
      'invoice_id' => 67990,
      'source' => 'SSF',
      'contribution_status_id' => 1,
    ),
  'api.website.create' => array(
      'url' => 'http://civicrm.org',
    ),
  'api.website.create.2' => array(
      'url' => 'http://chained.org',
    ),
);

try{
  $result = $api->Contact->create($params);
  print_r($api);
}
catch (CiviCRM_API3_Exception $e) {
  // handle error here
  $errorMessage = $e->getMessage();
  $errorCode = $e->getErrorCode();
  $errorData = $e->getExtraParams();
  return array('error' => $errorMessage, 'error_code' => $errorCode, 'error_data' => $errorData);
}

I suspect that handling passing in arrays would be easier done if we submit data to the interface as JSON rather than keyed POST values?

Will come back to this but didn't look any further yet - it's the weekend, and implementing what I needed without chained calls took me a third of the time it did to discover that chained calls weren't working

Do the API test cases get tested over the HTTP interface or just from within PHP?

I had a modified class.api that handled json_encoding.

I'm not sure why I didn't PR it, I'm swamped with the european election results (they suck) but will try to find it and PR or at least send to you for testing.

@Erik, definitely works over rest, I used from node.js
