braintree error 91507: cannot refund a transaction that is not settled

Not specified by the original author.

TL;DR

You cannot refund a transaction that has not settled yet. Void it instead: voiding cancels the authorization and releases the hold, which is the correct reversal for unsettled transactions. Only use refund after settlement.

91507 cannot refund a transaction that is not settled

Use this when

• A Braintree refund call returns error 91507.
• The transaction is authorized or submitted for settlement but not settled.
• You need to choose between void and refund in code.

Not for this skill when

• The transaction is settled and the refund still fails. That is a different error.
• You want to reverse a partial amount on an unsettled transaction. Void is all-or-nothing.

Steps

1. ('Check the transaction status. Verify: it is authorized or submittedforsettlement, not settled.', 'Call void on the transaction instead of refund. Verify: the void succeeds and the authorization is released.', 'Tell the customer the hold will drop off, usually within a few business days per their bank. Verify: support has the right expectation set.', 'In code, branch on status: void if unsettled, refund if settled. Verify: the branch is tested with both states.', 'If you need partial reversals on unsettled transactions, settle first is not an option; void the whole thing and re-charge the right amount. Verify: finance approves the re-charge.')

cannot refund unsettled transaction braintree

Symptom search.

Compatibility: Braintree transaction API, void and refund operations, all SDK versions.

Why it happens

Authorization and settlement are two steps: authorization holds the money, settlement moves it. A refund returns moved money, so it needs settlement to have happened. A void cancels the hold before money moves. 91507 is Braintree enforcing that distinction: refunding an authorization would be returning money that never left. The void path is faster for the customer too, since no money movement needs unwinding.

Edge cases / pitfalls

• Void is all-or-nothing. There is no partial void.
• A transaction submitted for settlement can still be voided until the settlement batch runs. Act quickly.
• Once settled, void is no longer possible. The branch must check status at call time.
• Customer messaging differs: "the hold will drop off" for voids vs "the refund is on its way" for refunds.

TL;DR: You cannot refund a transaction that has not settled yet. Void it instead: voiding cancels the authorization and releases the hold, which is the correct reversal for unsettled transactions. Only use refund after settlement.

Not specified by the original author.

TL;DR

Braintree's refund API only works on transactions that have settled (or are settling). Error 91530 means the transaction is still authorized or submittedforsettlement. If you need a full reversal right now, call Transaction.void instead. If you need a partial refund, wait until the transaction settles and then refund it.

Verbatim error

Cannot refund a transaction unless it is settled.

(Error code 91530, returned as a transaction validation error from Transaction.refund.)

When this applies

• You called Transaction.refund (any SDK: Python, Ruby, Node, PHP, Java, .NET) and got 91530.
• The transaction status is authorized or submittedforsettlement.
• You are trying to refund a test transaction in the sandbox shortly after creating it.

When this does NOT apply

• The transaction status is settling or settled and refunds still fail: something else is wrong (check refund_id for an existing refund).
• You want to reverse a transaction that already settled and was already refunded: this is a duplicate-refund problem, not 91530.
• Disputes or chargebacks: the refund API is not the path for those.

Fix

1. Read the transaction status

result = gateway.transaction.find(transaction_id)
print(result.transaction.status)

Expected output: one of authorized, submitted_for_settlement, settling, or settled. The fix depends on it.

2. Unsettled transaction, full reversal needed: void it

result = gateway.transaction.void(transaction_id)
print(result.is_success, result.transaction.status)

Expected output: True and status voided. Voiding works on authorized and submittedforsettlement transactions and cancels the whole amount. This is the correct move for full reversals of fresh transactions.

3. Unsettled transaction, partial refund needed: settle first, then refund

Partial refunds are impossible before settlement. In production, wait for the next settlement batch (usually within about 24 hours), then run:

result = gateway.transaction.refund(transaction_id, partial_amount)
print(result.is_success, result.transaction.type)

Expected output: True and a new transaction of type credit for the partial amount. In the sandbox, use the SDK's test-helper settle call to move the fixture to settling/settled before refunding.

4. Settling or settled transaction: refund normally

result = gateway.transaction.refund(transaction_id)
print(result.is_success)

Expected output: True. Full and partial refunds both work on settling and settled transactions.

Variant phrasings

91530 braintree refund

The same validation error; the fix is the same: void while unsettled, refund once settled.

Braintree refund of an authorized transaction fails

Authorized means funds are held but not captured. Refund cannot run against a hold, so Braintree returns 91530. Void the authorization instead.

Braintree refund of a submittedforsettlement transaction fails

The transaction is queued for the next settlement batch but has not settled yet. Either void it now (full reversal) or wait for the batch and refund after.

Why it happens

A Braintree refund creates a credit transaction against captured funds. Before settlement the money has not moved: the gateway only holds an authorization, so the only allowed reversal is a void, which releases the hold. Partial refunds additionally need the settled record because the final captured amount is what the partial is computed against.

Edge cases

• A transaction that is settling can be refunded, but voids may already be locked out at that point; if void fails, refund instead.
• Refunding twice: check transaction.refunded (or the refund_id field) before retrying. A second refund attempt is a different failure, not 91530.
• Settlement timing varies by merchant account and processor; do not hard-code "settles in exactly N hours" into retry logic.
• Sandbox transactions settle on a test schedule and can sit in submittedforsettlement for a long time; this is expected, not a bug.

Braintree error 91567: payment method nonce already consumed

TL;DR

A Braintree payment-method nonce is single-use: the moment it is consumed by a transaction, sale, or vault call, it is dead. Error 91567 means your server sent the same nonce twice. Generate a fresh nonce on the client for every attempt and make your server treat a consumed nonce as "get a new one," never as "retry with the same one."

braintree error 91567: payment method nonce already consumed

Steps

1. Find where the nonce is reused: search your server code for the transaction call and check whether retries, double-clicks, or a retry loop resend the same nonce value. Success check: you can point to the exact code path that submits the nonce twice.
2. Disable the pay button on first click and guard against double-submit on the client. Success check: rapid double-clicks produce one transaction attempt, not two.
3. On 91567, return a clear signal to the client to re-tokenize: generate a new nonce via Drop-in or the client SDK and submit again. Success check: the retry after 91567 uses a visibly different nonce string.
4. Make server-side retries nonce-aware: a retry must request a fresh nonce from the client (or fail the attempt and ask the shopper to resubmit), never replay the stored one. Success check: no code path sends a previously used nonce to the gateway.
5. Test the double-submit case deliberately: submit, then submit the same nonce again, and confirm the second attempt gets 91567 handled gracefully. Success check: the shopper sees "please try again" instead of a raw error.

When this applies

• Braintree returns validation error 91567 on transaction sale, vault, or verification calls.
• An agent-built checkout double-submits or retries with a cached nonce.
• You need the canonical single-use-nonce handling pattern.

When it doesn't

• The nonce is invalid or expired (different error codes); those are tokenization problems.
• A vaulted card is gateway-rejected; that is the issuer, not the nonce.
• Client-side Drop-in fails to produce a nonce at all; fix tokenization first.

Tool + version compatibility

Braintree server SDKs (all current versions), Braintree Drop-in UI / client SDK v3+, payment method nonces.

"braintree nonce already used"

Same error, same fix: nonces are one-shot by design.

"braintree 91567 retry"

Retrying with the same nonce can never succeed. The retry must mint a new nonce.

"braintree duplicate nonce submit"

Usually a double-click or a form resubmission. Client-side submit guards fix it at the source.

Why it happens

Braintree designed nonces as single-use tokens so a captured nonce cannot be replayed by an attacker. The tradeoff is that any accidental replay, double-submit, back-button resubmit, or naive server retry, looks exactly like a replay attack to the gateway. Agent-generated checkouts commonly store the nonce in a variable and reuse it across retries, which guarantees 91567 on the second attempt.

Edge cases / pitfalls

• A nonce consumed by a verification call is also dead; you cannot verify then transact with the same nonce.
• Nonces expire after a few hours even if unused; an old-but-unused nonce fails differently, so check the error code.
• 3D Secure flows consume and produce nonces at different steps; make sure your code threads the new nonce forward after each step.
• Log nonce prefixes (never full nonces) to trace reuse without storing sensitive values.
