Brevo

Probo reads your Brevo account’s users through the Brevo API so you can review who has access.

Caution

Create an API key (xkeysib-…) on the API Keys & MCP tab of Settings > SMTP & API. An SMTP key, created on the SMTP tab of the same page, will not work, because it authenticates Brevo’s SMTP relay rather than the REST API that serves the users endpoint. Leave the Create MCP server API key option off: activating it deactivates the key you just generated and issues an MCP version instead.

Prerequisites

• Probo organization administrator access
• The API Keys permission in Brevo, under SMTP & API (the account owner has it; only users with that permission can open the API Keys & MCP page and generate a key)
• A key created inside the Brevo account you want to review, since a key belongs to exactly one account

Collected Fields

Probo field	Brevo field	Notes
Name	email	The users endpoint returns no display name, so Probo uses the email address
Email	email
Role	feature_access	The access levels Brevo returns per feature area (marketing, crm, conversations, transactional, phone and any others), deduplicated and sorted. A feature set to none is dropped, so a user with access to nothing has no role
Admin	is_owner	Flagged as an administrator when is_owner is true. Brevo returns a boolean, and Probo also accepts the string "true"
Status	status	active is listed as active and any other value, such as pending, as inactive. A user Brevo returns without a status is left unknown
MFA	Not supported
Last login	Not supported
External ID	id	Stable identifier used to track the account across reviews. Falls back to the email address when the response has no id
Created at	Not supported

The account owner is listed alongside everyone invited to the account. An invitation that has not been accepted yet still appears in the list, marked inactive. A user returned without an email address is skipped.

Step 1: Create an API Key

1. In Brevo, signed in as the account owner or as a user with the API Keys permission, click your account dropdown and select Settings > SMTP & API > API Keys & MCP.
2. Click Generate a new API key, name it (e.g. Probo Access Review), and set an expiry date from 7 days to 1 year, or choose no expiration. Brevo API keys have no scopes, so every key has full access to the account.
3. Click Generate, copy the key (xkeysib-…), and click OK. It’s shown only once.

Step 2: Connect in Probo

1. In Probo, go to Access Reviews > Sources > Add Source.
2. Find Brevo, click API Key, paste the key, and click Connect.

The users endpoint returns no account name, so Probo lists the source under the fixed name Brevo and pulls the account’s users into your campaigns.

Troubleshooting

• Key rejected. Confirm it is an API key (xkeysib-…) from the API Keys & MCP tab and that it is still active. An SMTP key won’t work. A key also stops working once it reaches its expiry date, and Brevo expires any key that goes unused for 90 days.
• Generate a new API key is unavailable. Only the account owner and users with the API Keys permission, under SMTP & API, can open the API Keys & MCP page and create or delete a key.
• Calls stop working after the key worked once. Brevo can block API calls from unauthorized IP addresses. Under Settings > Security > Authorized IPs, disable API-key IP blocking for Probo Cloud. For a self-hosted deployment, you can instead authorize that deployment’s fixed egress addresses.
• Only the account owner appears. The Free and Starter plans include a single user seat, so those accounts have no other users to review. Otherwise, confirm the key was created in the account whose users you want to review: a key belongs to exactly one Brevo account, and an Admin account and each of its sub-organizations have their own keys.
