Connect Moneybird

Your application calls one EchoRelay URL. When Moneybird changes its API, you update the mapping, not your application.

How Moneybird signs requests

A personal API token, sent as a bearer token in the Authorization header. Moneybird also offers OAuth apps that act for each user; that route is not the one to use here.

Can you connect it today?

Yes, with a personal API token. Add a bearer-token credential with it.

A sample mapping

Your application sends the first request below. The mapping turns it into the body of POST /api/v2/{administrationId}/contacts, shown second.

Your request

{
    "company": "Acme BV",
    "firstName": "Lotte",
    "lastName": "de Vries"
}

What Moneybird receives

{
    "contact": {
        "company_name": "Acme BV",
        "firstname": "Lotte",
        "lastname": "de Vries"
    }
}

The mapping

{
    "$schema": "https://schemas.echorelay.dev/transform/mapping/v1.json",
    "root": {
        "type": "object",
        "id": "root",
        "properties": {
            "contact": {
                "type": "object",
                "id": "contact",
                "properties": {
                    "company_name": {
                        "type": "field",
                        "id": "company",
                        "path": "company"
                    },
                    "firstname": {
                        "type": "field",
                        "id": "first-name",
                        "path": "firstName"
                    },
                    "lastname": {
                        "type": "field",
                        "id": "last-name",
                        "path": "lastName"
                    }
                }
            }
        }
    }
}

The grammar, the answer mapping and the dry run are in the mapping docs.

What you bring

This is not a ready-made connector. You bring a sample request or Moneybird’s OpenAPI document, you or your agent write the mapping, and we run the integration you define.
