Tasks supported

Add Subscriber

Adds the form submitter as a contact on the chosen Laposta mailing list. Re-submissions update the existing subscriber rather than creating duplicates.

Pro features

The Pro Laposta integration adds custom field auto-load. Pick a list and AFI fetches every additional field defined on that list, exposing them in the mapping screen alongside Email and IP Address.

Conditional logic example

Subscribe to the “Newsletter NL” list only when the form’s language field equals “NL”. Other languages go to language-specific lists via separate integrations.

Troubleshooting

Integration doesn’t fire

Open AFI → Log and find the most recent entry. The log shows the request payload sent to Laposta and the response received, usually pointing straight at the cause.

Custom field not visible

Custom fields are available in the Pro version. The free integration includes Email and IP Address.
