Once your company is approved for Dintero Payout, you can start the process adding your merchants as sellers. You can choose to do this part from Backoffice, or through the API.

​
Onboarding your merchants from Backoffice

Once again, go to Settings → Sellers. Here, you will find a new button Add new Seller .
  1. Fill out preliminary info about your merchant.
When onboarding a company you will need to provide the country, organization number, currency and seller id.Add Seller form in Backoffice with the Company tab selected
  1. Once filled out, press Continue and you will get a link to send to your merchant.
Add new Payout Destination dialog showing the contract link

​
Onboarding your merchants through the API

  1. Fill out preliminary info about your merchant.
Use New seller approval to fill out information about the merchant. The type field decides which fields you send:
Set type to company, or leave it out. organization_number and country_code are required.
payout_destination_id, payout_reference and bank_accounts are required for both types. The rest of the flow is the same.
  1. Receive a link to send to your merchant.
The link will be in the response under links with rel=contract_url. While the merchant has not yet completed the declaration form and signed the agreement, the approval has case_status=WAITING_FOR_DECLARATION.

​
Handing over to your merchant

Now, take this link and send it to your merchant. This link will take your merchant to a similar KYC form to yours. If a form_submitter email was provided when creating the approval, the merchant will be notified via email.

​
Reminder emails

If the form is not completed (unsigned or undeclared), reminder emails are automatically sent on the following schedule:
  1. 24 hours after the initial notification
  2. 2 days after
  3. 1 week after
  4. 2 weeks after
  5. 4 weeks after
Once they’ve submitted their company declaration form and signed the agreement electronically our KYC department will take a look at the data and evaluate your application.

​
Seller approval

To know when the Seller is approved, you can create a webhook from Settings → Webhooks → Add webhook and choose approval_payout_destination_update.
See webhooks approval_payout_destination_update for example of data that will be sent to the webhook
Consider the Seller approved when the seller approval has been updated to case_status=ACTIVE. You can also poll the endpoint List seller approvals to see when the destinations are approved. Once the seller is approved, you can start creating sessions with splits.

​
Testing seller approval

In test mode (account IDs prefixed with T), you can skip the declaration form and KYC review:
  • Set payout_destination_description to AUTO_APPROVE, AUTO_DECLINE or AUTO_WAITING_FOR_SIGNATURE. See Auto-approve sellers.
  • Use a test bank account number in bank_accounts. See Test bank accounts.
You can technically create sessions with splits before the sellers being approved, but there is no guarantee that they will be approved.In the case that an unknown or unapproved seller is used, the plattform merchant will have to deal with the matter manually.
