Technical details about how we implement TransferWise and how to get started developing with it.

TransferWise integration can be used to automate expense payment as a way to provide one-click wire transfer for expenses.

Strong Customer Authentication

In order to create a new TRANSFERWISE_PRIVATE_KEY you'll need to generate a new key pair:

openssl genrsa -out private.pem 2048
openssl rsa -pubout -in private.pem -out public.pem

After that, you can encode the private key using base64 and save it as an environment variable:

TRANSFERWISE_PRIVATE_KEY=$(cat private.pem | base64 -w 0)

Developer Sandbox

API Token

  1. Sign up for a developer account sandbox.

    • Two-factor authentication (2FA) code for sandbox login is 111111.

  2. Add a new Token.

  3. Done, now you can copy your token!

Connect Account to your Host

  1. Manually create a ConnectedAccount with generated clientId and clientSecret:

    INSERT INTO "ConnectedAccounts" ("service", "token", "CollectiveId")
    VALUES (E'transferwise', token, hostCollectiveId);
    • We're currently defaulting to your Business profile if two profiles exists. If you have two profiles and want to use your personal one, make sure to add { "type": "personal" } to the data column of the created Conencted Account.
