subscription with call back xml ?

i wan t to use an online donation platform to subscribe my new member in membership pro, is this possible to use callback xml?

Folowing this method:

Link with Information Transfer and Transaction Recovery
See technical explanations of “link with information transfer”, prior. This integration allows you to recover the
transaction after.

The transaction information will be transferred (POST) in XML format to the URL of your choice (which will have
to be specified in parameters when calling the form).
Additional inbound parameters to send when calling the form:
 PersonalUrl (encrypted): the URL of your callback, example:
&PersonalUrl=http://www.mysite.com/jdel_callback.php(encrypted).
 PersonalId (not encrypted): Unique ID for your transaction, example:
&PersonalId=00000001(not encrypted).
Outbound parameters sent to your “PersonalUrl”:
 trx_xml (encrypted): xml of the transaction. See “callback return xml example.txt” in the sources of the
prototype to view an example.
 mode (not encrypted): Contains “TEST” or “PROD” whether the transaction was made in test or
production mode.
 PersonalId (not encrypted): Your unique ID.

Hi Ces

Basically, it is not supported in Membership Pro. So If you want to have this integration, I think you can write a custom component to receive this XML callback, then from the data received, you can insert this data into Membership Pro

In general, that's how it should work. However, I am afraid of it is quite complicated, and you will need to have a good developer to help you to write this code
