How to Send Mail via OnlineCheckWriter.com: A Step-by-Step Guide
Sending mail through OnlineCheckWriter.com is a straightforward process. Here's how you can do it:
1. Create a Payee
First, you need to create a payee. Use the following API endpoint:

POST {{baseUrl}}/payees
If the payee information already exists in the system, a new payeeId will not be generated. Instead, the existing payeeId will be returned.
Sample Payload:
- {
- "payees": [
- {
- "name": "Alison Gambala k",
- "nickName": "",
- "company": "",
- "email": "email@test.com",
- "phone": "900244400",
- "address1": "95113 Mark Street Rod",
- "address2": "",
- "city": "Sanjose",
- "state": "CA",
- "zip": "95113",
- "country": "US"
- }
- ]
- }
2. Retrieve the Payee ID
After creating the payee, store the payeeId in your database for future transactions.
3. If you don't know bank account id
GET {{baseUrl}}/bankAccounts
3. Create a Check
Use the retrieved payeeId and your bankaccount_id to create a check:
This will return a checkId, for example, RJ6qGAm5lJGE1rD.
4. Add Attachments (Optional)
If you need to add any attachments to the check, use this API:
Add Attachment API
5. Mail the Check
To mail the check, call the following endpoint:
Mail Check API
- {
- "mailChecks": [
- {
- "checkId": "RJ6qGAm5lJGE1rD"
- }
- ]
- }
