Let your agents send transactional emails, manage contacts, contact lists and subscriptions, and read message history, statistics and templates through the Mailjet API. ## Connection * **Authentication**: API key (API key:Secret key). Sign in at app.mailjet.com → API → API Key Management → Primary API Key → Generate Secret Key. Mailjet uses two values: the API Key (public) and the Secret Key (private). The secret key is shown only once — copy it right away. Enter the credential as APIKEY:SECRETKEY (the two values joined by a colon). See [Mailjet's documentation](https://dev.mailjet.com/email/reference/). ## Read actions (9) | Action | Description | | ---------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `get_api_key_info` | List the API keys of the account with their settings — the cheapest call to check that the credential works. | | `get_contact` | Retrieve one contact: status, creation and last-activity timestamps. Use list\_contacts or list\_list\_recipients (filtered by ContactEmail) to find the numeric ID. | | `get_contact_data` | Retrieve all contact properties and their values for one contact. | | `get_message_history` | Retrieve the event history of one message — sent, opened, clicked, bounced, spam, unsub — with timestamps. | | `list_contact_lists` | List the contact lists of the account with their subscriber counts. Returns each list numeric ID, needed by manage\_contact\_lists. | | `list_contacts` | List contacts of the account. Filter by ContactsList to see the members of one list. Returns each contact numeric ID, needed by the other contact actions. | | `list_list_recipients` | List the contact-to-list memberships with their subscription status. Filter by ContactEmail to find the numeric ID of a contact from its email address. | | `list_messages` | List sent messages with their delivery status. Filter by contact, campaign, custom ID or time window. Returns each message numeric ID, needed by get\_message\_history. | | `list_templates` | List the email templates available to the account. Returns each template numeric ID, usable as TemplateID in send\_email. | ## Write actions (5) | Action | Description | | ---------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `create_contact` | Create a contact in the global contact list. Email: string, required, must not already exist in the account. Name: string, optional, free-text display name. IsExcludedFromCampaigns: boolean, optional — true adds the contact to the marketing exclusion list. Creating a contact does not subscribe it to any list: call manage\_contact\_lists afterwards. | | `create_contact_list` | Create a contact list. Name: string, required, must be unique across the account. The list is created empty — add contacts to it with manage\_contact\_lists. | | `manage_contact_lists` | Add, remove or unsubscribe one contact across several contact lists in a single call. contact\_id: string, the numeric contact ID (the contact must already exist). ContactsLists: array of objects, each \{ ListID: integer, Action: one of "addforce" (add and force-subscribe), "addnoforce" (add, keep an existing unsubscribed status), "remove" (remove from the list), "unsub" (keep in the list but unsubscribe) } — NOT an array of list IDs. | | `send_email` | Send one transactional email through Send API v3.1. From: object \{ Email: string (required, an activated sender of the account), Name: string }. To: array of objects \{ Email, Name }, at least one. Subject, TextPart, HTMLPart: strings — send TextPart and/or HTMLPart, or a TemplateID instead. TemplateID: integer (bare number, not an object). TemplateLanguage: boolean, set true to interpolate Variables into the template. Variables: object of key/value pairs. Cc, Bcc: arrays of \{ Email, Name }. ReplyTo: object \{ Email, Name }. CustomID: string tag retrievable later with list\_messages. SandboxMode: boolean, true validates the payload without delivering anything. | | `update_contact_data` | Replace the contact properties of one contact. contact\_id: string, the numeric contact ID or the contact's email address. Data: array of objects, each \{ Name: string, Value: string } — Name is the property name, which must already exist on the account as a contactmetadata entry. The array replaces the stored properties entirely. | ## Permissions Every action above must be explicitly granted to an agent before it can be used. See [Permissions](/integrations/permissions) for the grant model and [Security](/integrations/security) for how credentials are protected.
