Recurring payments, also known as merchant-initiated transactions (MITs), let a customer approve once, then let you charge them later without asking again. Each charge is a normal payment session, so capture, void, refund, webhooks, and settlement work exactly as they do for every other Payment Acceptance payment. Customers can stop future charges at any time.

What you can build

Subscriptions

Bill monthly or annual plans without sending the customer back to checkout every cycle.

Usage-based billing

Bill for metered usage at the end of each billing period, for any amount within your limits.

Auto top-ups

Refill a prepaid balance or credits automatically when it runs low.

One-click repeat purchases

Let returning customers pay without going through checkout again.

Choose a source

Customers can pay from their Coinbase account or from a self-custody wallet. You can offer both.

Charge a Coinbase account

Recurring charges from a Coinbase account use the Pay with Coinbase flow. After the first charge, your billing job runs it without the customer.
  1. Link the account and take the first charge while the customer is present. Start the first charge’s challenge with initiator: "merchant", not customer. See Link the customer’s Coinbase account and the scenario table.
  2. Refresh the access token only when it has expired or is about to. Check expires_at before each charge. Each refresh invalidates the previous refresh token, and sending an invalidated refresh token ends the link with invalid_grant. Run one refresh at a time per customer, and save the new refresh token before you use the new access token. See Refresh tokens.
  3. Check available_to_send before you create the session. See Check the customer’s USDC balance.
  4. Authorize off-session with initiator: "merchant" and enforce2fa: false. See Charge without the customer present.
  5. Stop billing when the link ends. A 401 on authorization can mean the access token expired, so refresh once and retry. The link has ended when the refresh returns invalid_grant, or when you receive oauth.token.revoked or identity.user.deleted. After invalid_grant or oauth.token.revoked, the customer must link again.

Charge a self-custody wallet

The customer approves a mandate once: their revocable consent for you to pull payments from their wallet, within limits you set. Funds stay in their wallet until you charge. Approving and paying are gasless. Customers can approve from Base, Ethereum, Arbitrum, Optimism, Polygon, or Solana. Solana uses the network name solana in every environment, including sandbox.

1. Create a mandate

Create one mandate per customer relationship, such as one per subscription. Set spending limits that fit your billing model.
Coinbase generates the mandateId. You can’t set it yourself, so save it with your customer record. You’ll need it to authorize every payment. To attach your own identifiers, such as a customer or subscription ID, use metadata.
The mandate starts in created status. You can’t authorize payments with it until the customer approves it.

2. Get the customer’s approval

The customer approves the mandate once from their self-custody wallet, for example during signup or checkout. Redirect the customer to the mandate’s url, or embed the approval in your page by calling render({ mandateId }) on the <coinbase-payment> web component. Coinbase connects the wallet, picks the best-funded network, and collects the signature. See Hosted Checkout for setup. The approval returns in pending status and confirms onchain shortly after. Wait for the acceptance.mandate.approval_succeeded webhook before you authorize a payment. At that point the mandate moves to approval_succeeded and its source shows the wallet address and network the customer approved from. If approval fails, the mandate moves to approval_failed and the customer can try again.
You only need these endpoints if you’re not using the hosted page or embedded component. They don’t use your API key, because the customer’s wallet signature is the proof of consent, so you can call them from your frontend. The flow mirrors wallet authorization.
  1. Get approval options for one to five of the customer’s wallet addresses:
    Coinbase returns at most one option, choosing the address and network with the highest stablecoin balance, including Solana. Pass network only when the customer must approve from one network. The Solana network name is solana in every environment, including sandbox. Addresses that can’t be used appear in ineligibleAddresses with a reason, such as insufficient_funds.
  2. Sign the payload for the option’s type:
  3. Submit the signature:
    The example signature is an EVM hex signature. A Solana approval uses the same request body. Its signature is the base58 string from Solana signatures.
Sign and submit payloads from a single options response. Each response includes fresh signing data, so don’t cache options.Revocation uses the same signing rules. Call GET /v2/mandates/{mandateId}/revocations/wallet/options, have the customer sign the returned payload (eip2612 on EVM, solana_subscription on Solana, where the transaction is revokeDelegation), and submit the signature to POST /v2/mandates/{mandateId}/revocations/wallet.

3. Authorize a payment

For each payment, create a payment session for the amount due, then authorize it with the mandate. The customer doesn’t need to take any action.
The authorization returns in pending status and moves to succeeded or failed. An authorization is rejected before any funds move if the mandate isn’t usable or the amount breaks the spending limits. See Mandate errors. If the customer’s wallet doesn’t hold enough to cover the payment, the authorization fails with insufficient_funds. See Prevent failed mandate payments for how to catch that before billing day.

After you authorize

From here, charges from both sources follow the standard lifecycle:
  • Auto-capture suits most recurring charges, because you’ve already delivered the service or are about to.
  • Voids and refunds return funds to the source: the customer’s Coinbase account, or the wallet and network they approved from.
  • Idempotency keys let your billing jobs retry safely. Always send X-Idempotency-Key so a retry never charges twice. See Idempotency.
  • Failed authorizations can’t be retried on the same session. To try again, create a new payment session and authorize it with a new X-Idempotency-Key.

Mandate spending limits

Every mandate has a policy that caps what you can authorize. Coinbase checks the policy on every authorization. All limits are optional. Any limit you omit gets a Coinbase default, and limits above Coinbase’s maximums are lowered to the maximum. The response always shows the limits that apply. An authorization over a limit is rejected with 422 mandate_policy_violation, and no funds move. We recommend setting your own limits that match your billing model. Your business is responsible for payments authorized with its mandates, so tight limits protect your customers from misuse. Leave some headroom above your expected payment amounts for plan upgrades, taxes, or usage spikes. Mandate terms can’t be edited after you create the mandate. To change them, cancel the mandate, create a new one, and ask the customer to approve it.

Ending a mandate

There are two ways to end a mandate, and they’re independent. When a customer ends their subscription, cancel the mandate so no further payments can be authorized, and point them to revocationUrl if they also want to remove the wallet approval. If a customer removes the approval directly from their wallet, your next authorization fails.

Prevent failed mandate payments

A payment fails with insufficient_funds when the customer’s wallet doesn’t hold enough of the mandate asset on the approved network. No funds move and the mandate stays usable, but the payment doesn’t go through until you retry. Unlike a card, a wallet’s balance is public onchain, so you can spot a shortfall before you authorize. We recommend checking the balance in your billing job before every mandate payment and letting the customer know when they’re short. Coinbase doesn’t contact your customers.

Check the balance before you authorize

  1. Get source.address, source.network, and source.asset from the mandate, either from the acceptance.mandate.approval_succeeded webhook or GET /v2/mandates/{mandateId}. Payments are only pulled from this wallet, on this network, in this asset.
  2. List the wallet’s balances on source.network with the Token Balances API:
    The Token Balances API covers Base and Ethereum. For mandates approved from Arbitrum, Optimism, or Polygon, read the USDC balance of source.address with your own node or indexer, then continue from step 4.
  3. Find the USDC entry by token.contractAddress (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base, 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum), not by symbol. Results are paginated: if the response includes nextPageToken, pass it as pageToken to get the next page. If USDC isn’t on any page, the balance is zero.
  4. Compare the balance to the amount due. The API returns amount as an integer in USDC’s smallest unit, where 1 USDC is 1,000,000 units (decimals: 6). Payment amounts like 19.99 are in whole USDC, so convert the amount due before you compare: 4100000 is less than 19990000, so the customer is 15.89 USDC short.
  5. If the balance is below the amount due, tell the customer how much to add and the address, network, and asset to send it to. Funds on another network or in another token don’t count.

If the payment fails anyway

A passing check doesn’t guarantee the payment goes through, because the customer can move funds after you check. When an authorization fails, the acceptance.payment_session.authorization_failed webhook carries the reason in data.authorization.error.code. If the reason is insufficient_funds, no funds moved and the mandate is still usable. To try again, create a new payment session and authorize it with the same mandateId and a new X-Idempotency-Key. Other failure reasons, such as a revoked mandate, need a different response. See Mandate errors.

Mandate statuses

status reflects the most recent action on the mandate. To decide whether you can authorize a payment with a mandate, check its timestamps rather than relying on status alone. A mandate is usable when approvedAt is set, canceledAt and revokedAt are empty, expiresAt is empty or in the future, and no revocation is in progress (status isn’t revocation_pending). For example, a mandate in revocation_failed is still usable because the approval was never removed.

Mandate errors

These errors mean Coinbase rejected a mandate authorization before any funds moved. Coinbase checks the mandate in this order and returns the first match. Standard payment session errors, such as an expired authorization window, also apply. An insufficient_funds failure arrives asynchronously through the acceptance.payment_session.authorization_failed webhook rather than as an HTTP error. See Prevent failed mandate payments.

Webhooks

Charges from both sources use the existing payment session events. For a Coinbase account, also subscribe to the OAuth and identity events to know when a link ends. For a wallet, subscribe to acceptance.mandate.* events to track approvals and cancellations: Every mandate event’s data contains the full mandate. Approval events also include approval, and revocation events include revocation, each with an error when the attempt fails. See example payloads and Webhooks for setup.
