when I try to chain commands in the content body of a POST, the contact is created fine, but the chained address is not created. I am not OK with passing sensitive donor information as parameters in the URI (which is against the HTTP protocol specifications for a valid reason), so I need to figure out what the expected syntax is for body contents:

contact_type=Individual&first_name=joe&last_name=blow&api.Address.create={"location_type_id":"Home","street_address":"123 somewhere st"}

passed in the URI, the above works fine...

in the header I'm specifying Content-Type: application/x-www-form-urlencoded and json=1 in the URI


CiviCRM allows you to send api params in POST by encrypting the params in json. Here is an example on how you can build api params used in REST call

http://www.domain.org/sites/all/modules/civicrm/extern/rest.php?entity=Contact&action=create&api_key=userkey&key=sitekey&json={"contact_type":"Individual","first_name":"test","last_name":"test","api.Address.create":{"location_type_id":"Home","street_address":"123 somewhere st"}}

You can use api explorer to build your params.

  • Quick question: When you say "encrypt" do you mean "encode"? It's not actually encrypted, right? – Demerit Apr 8 at 23:10
  • I meant json encoded – Pradeep Nayak Apr 8 at 23:11
  • you've missed the point of my question. I know you can chain the parameters via the URI. This is totally insecure and breaks the HTTP specification for POST. Isn't anyone else concerned that sensitive data will appear in access logs, or could be sniffed via the URI? – Mike Stairs Apr 9 at 17:18
  • I was told we could instead pass these parameters within the content body, which works up to a point. Any chained data is ignored, only the base entity is created. If you could in fact encrypt the parameters that would actually alleviate my concerns. – Mike Stairs Apr 9 at 17:18

    I believe that you can pass all those params into POST rather appending to url. – Pradeep Nayak Apr 10 at 8:09

@pfigel in chat.civicrm.org responded that this is possibly a problem with encoding. This works for him:

curl -X POST 'http://civicrm.example.com/sites/all/modules/civicrm/extern/rest.php' -H 'Content-Type: application/x-www-form-urlencoded; charset=UTF-8' --data 'api_key=hunter2&key=hunter2&entity=Contact&action=create&json=%7B%22contact_type%22%3A%22Individual%22%2C%22first_name%22%3A%22John%22%2C%22last_name%22%3A%22Doe%22%2C%22api.Address.create%22%3A%7B%22location_type_id%22%3A%22Home%22%2C%22street_address%22%3A%22Main+Street%22%7D%7D'
