Batch Payouts let you create up to 5,000 payouts for different users with one request. The batch executes each payout independently, giving every item its own transfer, status, and idempotency guarantees while still letting you manage the workflow as a unit.

​
Requirements

  • A Dots account with an App and API credentials.
  • Each user in the batch must already exist in your workspace and be allowed to receive payouts on the selected rail.
  • Every batch item must set fund=true, which moves funds before the payout is issued.
  • Plan to handle partial failures by inspecting each item’s error_code and error_message.

​
1. Build the batch payload

Each batch contains a shared metadata object and a list of payout items. Every item must use a unique idempotency_key; duplicates are rejected during validation.

​
Batch-level fields

FieldRequiredDescription
items✅Array of payout requests. Min 1, max 5,000 items.
idempotency_keyOptionalUUID to prevent duplicate batch submissions.
metadataOptionalAttach custom context (string or key/value object) to the batch.

​
Item fields

FieldRequiredDescription
user_id✅Target user’s ID.
amount✅Amount in cents to pay the user.
platform✅Rail to use (for example ach, paypal, venmo, default).
account_idOptionalACH / bank account to use when a user has multiple accounts on the same rail.
idempotency_key✅UUID to deduplicate this specific payout. Must be unique within the batch.
fund✅ (true)Batch payouts currently require true. Transfers funds before issuing the payout.
tax_exemptOptionalExclude the payout from 1099 calculations.
payout_fee_partyOptionalOverride who pays fees (user or platform).
metadataOptionalCustom context specific to the item. Returned in results for easy reconciliation.

​
2. Create the batch

Use POST /v2/payout-batches with your App credentials. Reuse the same idempotency_key to safely retry the request. 
curl --request POST \
  --url https://api.senddotssandbox.com/api/v2/payout-batches \
  --header 'Authorization: Basic <client_id:api_key>' \
  --header 'Content-Type: application/json' \
  --data '{
    "idempotency_key": "a7bb54d2-7342-4d13-a8aa-9d999753128b",
    "metadata": {
      "batch_type": "weekly_payouts",
      "week": "2024-08"
    },
    "items": [
      {
        "user_id": "a169451c-8525-4352-b8ca-070dd449a1a5",
        "amount": 1000,
        "platform": "paypal",
        "idempotency_key": "c3d4e5f6-g7h8-i9j0-k1l2-m3n4o5p6q7r8",
        "fund": true,
        "tax_exempt": false,
        "metadata": {
          "invoice_id": "INV-123"
        }
      },
      {
        "user_id": "b269451c-9625-5452-c9db-171ee559b2b6",
        "amount": 2500,
        "platform": "ach",
        "account_id": "c369451c-a725-6552-d0ec-272ff669c3c7",
        "idempotency_key": "d4e5f6g7-h8i9-j0k1-l2m3-n4o5p6q7r8s9",
        "fund": true,
        "tax_exempt": false
      }
    ]
  }'
The batch is queued for execution immediately. Statuses progress from created → processing → paying_out → completed as transfers are issued.

​
3. Track batch processing

​
Check the batch summary

Poll GET /v2/payout-batches/{payout_batch_id} to monitor the batch-level status and metadata. 
curl --request GET \
  --url https://api.senddotssandbox.com/api/v2/payout-batches/e5d5863a-498d-4551-a3dc-e31012503f23 \
  --header 'Authorization: Basic <client_id:api_key>'

​
Retrieve per-item results

Call GET /v2/payout-batches/{payout_batch_id}/results for detailed outcomes. Set include_request=true to echo the original request payload for each item. 
curl --request GET \
  --url "https://api.senddotssandbox.com/api/v2/payout-batches/e5d5863a-498d-4551-a3dc-e31012503f23/results?include_request=true" \
  --header 'Authorization: Basic <client_id:api_key>'
Use the per-item transfer.status to reconcile payouts that succeeded (settled / processing) versus those that require follow-up. Items that fail keep their error_code and can be retried with a new idempotency key once the underlying issue is resolved.

​
4. List historical batches

GET /v2/payout-batches returns paginated batches created by your App. Use limit, starting_after, and ending_before to page through older entries. 
curl --request GET \
  --url "https://api.senddotssandbox.com/api/v2/payout-batches?limit=10" \
  --header 'Authorization: Basic <client_id:api_key>'

​
Best practices

  • Use idempotency everywhere: Provide both batch- and item-level keys so you can safely retry without creating duplicate payouts.
  • Handle partial failures: Inspect each item’s error_code/error_message and requeue only the failed items with new idempotency keys.
  • Monitor transfers: Subscribe to payout and transfer webhooks to track asynchronous status changes beyond the initial batch response.
  • Respect rate limits: Large batches may take time to execute; poll no more than once every few seconds and back off when the batch is still processing.
