Workflow Description
This workflow consists of:
a webhook trigger
a set node
an if node
an HTTP request

The Webhook Trigger
The webhook triggers when a person is updated in CentralStationCRM.

The persons data is sent to n8n, including the company name and the address.

The Set node
This node filters the webhook data for just the data the EchtPost node needs. It also transforms the country field to the associated country code (i.e. "Deutschland" -> "DE")

The if node
This node checks if there is an "EchtPost" tag in the persons data.
-> if false: do nothing
-> if true: go to HTTP request

The HTTP Request
This node sends the persons name, address and country code alongside with the id of the EchtPost template (inserted manually in the node) to EchtPost. It also needs an E-Mail-Adress for a confirmation mail.

The data starts a "Mail in 3 days" process with the EchtPost service, which mails a postcard with that template to the person.

Preconditions
For this workflow, you need:
a CentralStationCRM account with API access
an EchtPost account with API access
an EchtPost template, with a message, and the templates ID
