API referenceBilling

Billing

The team's plan, usage, invoices and add-ons, and the two hosted pages where a customer pays.

Who can call it

Two reads are open to a scope; everything else on this page needs a full_access key. A scope can read billing; nothing but a full_access key can change it.

What each credential can reach on the billing routes
Credential	The two reads	Everything else
`full_access`	200	200
`sending_access`	`401 restricted_api_key`	`401 restricted_api_key`
OAuth token with `billing:read`	200	`403 invalid_permission`
OAuth token with every scope	200	`403 invalid_permission`

The reads are GET /billing and GET /billing/invoices. No OAuth scope reaches the rest: a token holding every scope in the catalogue is still 403 invalid_permission on checkout, the portal, a plan change, pay-as-you-go, both spend-cap routes, both add-on routes and both limit-request routes.

Hosted pages

POST /billing/checkout and POST /billing/portal answer a URL. Send the customer's browser there: the card is entered on that hosted page and never passes through this API.
return_url must be an absolute https URL. The browser comes back to it with checkout=success or checkout=cancelled appended; without one it comes back to the dashboard.
A checkout URL stops working at its expires_at. Ask for a new one.

A few changes are refused for a key even when it is full_access: anything that would turn off the team's single sign-on — removing the sso add-on, or a plan change that drops it — needs a signed-in admin, because it decides who may sign in.

Endpoints

Retrieve billing

GET /billing

The plan, this period's usage, payment state, add-ons and any pending change.

payment_method says whether a card is on file and shows its brand and last four digits. The card itself never leaves the payment provider.
usage.emails_today counts today's sends against usage.daily_limit, the most this team can send today. The count starts again at 00:00 UTC. daily_limit is null when there is no daily limit.
usage.monthly_limit is the most this team can send this month before a send is refused. It can differ from usage.included_emails, the plan's allowance, when a limit was set for the team or the sending tier's cap is lower than the plan. null when nothing caps the month.
checkout_available is true when the team has no subscription yet, so POST /billing/checkout is the way to start one. paid_plan is the other question: a team can hold a subscription for inbox storage alone while still on the free plan.
usage.marketing_* is the marketing meter, its own pool: campaign recipients never count against usage.emails, and POST /emails never counts against marketing_emails.
inbox_seats counts Inbox mailboxes past the ones the plan includes; dedicated_ip puts the volume a dedicated IP is recommended from beside this team's own 30-day daily average.
storage_addon_purchase says how to buy inbox storage right now — add_item through POST /billing/addons, checkout through POST /billing/checkout with addon_code, held when the team already has it, or unavailable when it cannot be bought at the moment. Both purchase calls answer 503 service_unavailable while it is unavailable, before anything is charged or recorded.

The team's invoices, newest first, with links to the hosted invoice and its PDF.

Start a subscription

POST /billing/checkout

A hosted checkout page for a plan, or for inbox storage on its own. Send the customer's browser to its `url`.

Body

plan_codestring
The plan to start the subscription on, such as pro_50k or scale. Send this or addon_code, never both.
addon_codestring
Buy an add-on on its own, leaving the team on the plan it is already on: inbox_storage_100gb or inbox_seat. Send this or plan_code, never both.
return_urlstring
Where the browser comes back to, with checkout=success or checkout=cancelled appended. Absolute https only. Defaults to the dashboard page return_to names.
return_tostring
Which dashboard page to come back to when there is no return_url: plan (the default), inbox or inbox_settings.

1 more field (quantity)

quantityinteger
Units to buy, 1–100, with addon_code only. Defaults to 1; only inbox_seat is sold by the unit.

The customer enters their card on the hosted page. Card details never pass through this API.
A return_url that is not absolute https is 422 validation_error.
Send exactly one of plan_code and addon_code. Neither is 422 missing_required_field; both is 422 invalid_parameter.
addon_code: "inbox_storage_100gb" buys 100 GB of inbox storage without a plan. The subscription it creates carries only that add-on, and POST /billing/plan can add a plan to it later.
A team that already has a subscription is 422 validation_error: it changes its plan with POST /billing/plan and buys add-ons with POST /billing/addons.
Called with an API key, no email address is sent to the payment provider: the customer types one on the hosted page.

An upgrade takes effect at once, with prorations. A downgrade is scheduled for the end of the period and shows in pending_change.
Free to paid is a checkout, and paid to free is a cancellation in the portal, so both are refused here.
A change that would turn off the team's single sign-on is refused for an API key: a signed-in admin makes it.

Set pay-as-you-go

It is on by default once the project is on a paid plan with a payment method on file. Setting it here makes it your choice, and it is not changed for you again.
Switching it on needs a plan with an overage rate and a payment method on file; otherwise 422 validation_error names what is missing.
It raises only the monthly quota — never the daily cap or a restricted team's limits. There is no overage ceiling; the project's spend cap still applies.

Read the spend cap

GET /billing/spend-cap

The most this project may send this month, the rungs it warns at, and what it has sent.

used_emails counts billable recipients on both meters, so a campaign and a receipt draw on the same cap.
A project that has set no cap of its own is held to ten times its monthly allowance, which is what is_default reports.

Set the spend cap

POST /billing/spend-cap

Set how much this project may send in a month, and when to be warned.

Body

emailsintegerRequired
The most this project may send in a month, in billable recipients. 0 pauses it on its next message.
alert_pctsinteger[]
Whole percentages of the cap to be warned at, one to eight of them. Omit to leave the current rungs alone.

Reaching the cap pauses this project's sending and leaves every other project on the account untouched.
Saving takes effect at once: a cap above the month's usage lifts a pause the cap caused, and a cap at or below it pauses the project there and then.
While it is paused, a send answers 429 monthly_quota_exceeded. Raising the cap starts it again, and so does the next month.

Ask for a higher sending limit

POST /limits/requests

Ask to send more. Small, safe increases are granted in the same request.

Body

requested_dailyinteger
The daily limit you would like, in emails a day. The only ask that can be granted automatically.
requested_monthlyinteger
The monthly limit you would like. Always read by a person: a monthly allowance is part of the plan.
expected_volumeinteger
Emails a month you expect to send at peak.
use_casestringRequired
What this project sends and why it needs more room. At most 1,000 characters.

An ask for a daily limit inside the band — at most twice what is in force, never past the ceiling of the project's sending tier, after its first week, and only while its delivery numbers are good — is approved in the same response and the new limit is already in force.
Anything else is pending: somebody here reads it, and decision_reason says why it was not automatic. A project whose sending is being held down is declined, with the reason.
Asking again while one is still pending answers with the ask already open rather than opening a second.

Response 200

Every add-on is an item on the team's subscription, so a team without one is 422 validation_error carrying details.next: "checkout" — POST /billing/checkout starts a subscription, and for inbox_storage_100gb it can buy the add-on on its own.
Everything except inbox_storage_100gb also needs a paid plan, so a team that bought inbox storage on its own is still refused the rest of the catalogue.
dedicated_ip is billed from now and normally reaches active within the request; it stays provisioning only while no address is free. Warm-up then runs on its own, and GET /billing shows it.
For inbox_seat, quantity must equal the team's open mailboxes minus the ones the plan includes: seats follow the mailboxes.
A marketing plan replaces any other marketing plan the team holds, in the same call, and takes quantity 1.
sso needs the Scale plan or above, and is included on Enterprise.

Remove an add-on

DELETE /billing/addons/{addon_code}

Take an add-on off the subscription, with a proration.

Path parameters

addon_codestringRequired
Any add-on code POST /billing/addons accepts.

Removing extra_domains_100 deletes no domain: the lower limit only refuses the next one you add. Removing a marketing plan likewise keeps the contacts you hold and refuses the next one past the plan's own limit.
Removing sso turns single sign-on off, so an API key is refused it with 403: a signed-in admin removes it.
