Poll this endpoint to follow mailboxes after [Order Mailboxes](https://developer.lemlist.com/api-reference/endpoints/domains/order-mailboxes.md). Canceled mailboxes are not listed. > [!WARNING] > > `active` means the mailbox exists at the provider, not that it can send yet. SMTP mailboxes, and Google Workspace mailboxes on a domain bought or transferred through lemlist, are connected automatically. Microsoft 365 mailboxes, and Google Workspace mailboxes on a domain connected from your own registrar, must be connected by their user in the lemlist app (Settings > Sending) before campaigns can use them. ## OpenAPI ````yaml get /domains-core/mailboxes openapi: 3.0.0 info: title: lemlist API version: 1.0.0 description: >- Welcome to the lemlist Developer Documentation. lemlist is very customizable and open. You'll find on this page all the API and integration you can do with lemlist. # Rate Limit lemlist's API rate limits requests in order to prevent abuse and overload of our services. Rate limits are applied on all routes and per API key performing the request. The rate limits are **20** requests per **2** seconds. The response provides any information you may need about it: | Header | Description | | --- | --- | | Retry-After | The number of seconds in which you can retry | | X-RateLimit-Limit | The maximum requests in that time | | X-RateLimit-Remaining | The number of remaining requests you can make | | X-RateLimit-Reset | The date when the rate limit will reset | _Example of values for the rate limit headers_ ``` json { "Retry-After": 2, "X-RateLimit-Limit": 20, "X-RateLimit-Remaining": 7, "X-RateLimit-Reset" : "Tue Feb 16 2021 09:02:42 GMT+0100 (Central European Standard Time)" } ``` # Definitions ## Team A team is the entity of lemlist that can handle users and billing. ## Credits Credits are the coins a team uses to enrich emails, LinkedIn URLs, etc. via the enrich route. Each enrichment feature needs a certain amount of credits to run. ## User You use a user account to connect to lemlist and send messages via the connected emails or LinkedIn account. ## Campaign A campaign is the entity to automate outreach. A campaign has multiple sequences composed of steps. ## Lead A lead is a person that you try to contact via a campaign. ## Activity An activity is the history of all the steps. ## Unsubscribe An unsubscribe occurs when a person decides they don't want to receive emails from you anymore. # Authentication All API routes use the dedicated subdomain `api.lemlist.com`. lemlist uses API keys to allow access to the API. You can get your lemlist API key at our [integration page](https://app.lemlist.com/settings/integrations). You need to add the `Authorization` header using the `Basic` authentication type. `login:password` **where the login is always empty and the password is the API key**. ⚠️ **Don't forget to add the semicolon (**`:`**) before your API key in curl command.** > To authorize, use this code: ``` shell curl https://api.lemlist.com/api/team \ --user ":YourApiKey" ``` **Make sure to replace** **`YourApiKey`** **with your API key.** # Give feedback If you want to report a bug, ask for data, or share with us a use case, please fill this [form](https://lemlist.typeform.com/to/mfVlkyGf). It will help us centralize your needs! servers: - url: https://api.lemlist.com/api security: - basicAuth: [] tags: - name: Enrichment Providers description: >- The data providers lemlist can call to find an email or a phone. Internal providers are paid with lemlist credits and always available. External providers run on your own account: connect one by saving its API key, and it becomes available to your waterfalls. `GET /enrichments/providers` is the catalog of provider ids accepted by the waterfall endpoints. - name: Enrichment Waterfalls description: >- Control which data providers lemlist calls when enriching a contact, and in which order. A waterfall is an ordered list of providers for one enrichment `type` (`email` or `phone`). Providers are tried one after the other until one returns a result. Every team has exactly one default waterfall per type (`isDefault: true`). While its `editor` is `lemlist` it follows the lemlist behaviour: providers you connected with your own API key are tried first, then internal providers in a random order. Once a team member edits its provider list, `editor` becomes that user's id and the list is followed as is; resetting it hands it back to `lemlist`. Custom waterfalls (`isDefault: false`) carry `conditions` on the contact being enriched, keyed by contact property; every key present must match. When a contact is enriched, lemlist runs a single waterfall: the custom waterfall of the requested type whose conditions match the contact, or the default waterfall when none does. If several match, the one with the most condition keys wins, then the most recently updated. Only that waterfall runs; when it finds nothing, the enrichment ends without falling back to another one. paths: /domains-core/mailboxes: get: tags: - Domains summary: List Domain Mailboxes description: >- Lists the mailboxes bought on the team's lemlist domains, newest first, canceled ones excluded. operationId: listDomainMailboxes parameters: - name: domainId in: query required: false description: Only the mailboxes of this domain example: dom_Kd8Wq2Lr5Tx9Mz3Pv schema: type: string responses: '200': description: The mailboxes content: application/json: schema: type: object properties: mailboxes: type: array items: $ref: '#/components/schemas/DomainMailbox' example: mailboxes: - _id: dem_Rb4Nc7Fy1Hs6Jq0Wt email: john@getacme.com domainId: dom_Kd8Wq2Lr5Tx9Mz3Pv status: active provider: google assignedToUserId: usr_Ye6Ta3Uo8Ic1Mn7Bh createdAt: '2026-01-15T10:31:00.000Z' '400': description: '`domainId` is not a domain id' content: application/json: schema: $ref: '#/components/schemas/ApiErrorMessage' example: error: >- Match error: Failed Match.OneOf, Match.Maybe or Match.Optional validation '401': description: Unauthorized - invalid or missing API key content: application/json: schema: $ref: '#/components/schemas/ApiErrorMessage' example: error: Unauthorized '500': description: Internal server error content: application/json: schema: $ref: '#/components/schemas/ApiErrorMessage' example: error: Internal error components: schemas: DomainMailbox: type: object description: A mailbox bought on a lemlist domain. properties: _id: type: string description: Unique mailbox identifier example: dem_Rb4Nc7Fy1Hs6Jq0Wt email: type: string format: email example: john@getacme.com domainId: type: string example: dom_Kd8Wq2Lr5Tx9Mz3Pv status: type: string enum: - ordered - paid - registered - pending - active description: >- Setup progress. `ordered`: waiting for the domain to be ready and for payment. `paid` to `pending`: being created at the provider. `active`: created.
