Every item follows `CreateContactInput`, and one invalid item rejects the whole request with 400. Item errors are grouped under `details.fieldErrors.contacts` without naming the index, so validate items on your side first. New contacts are created `pending`. **Deduplication.** * Items with the same phone key are collapsed and the first one wins. Email-only items are keyed by their address. * Phones that already exist in the campaign are skipped, and their stored data is **not** updated (unlike the single-contact endpoint). * Phones removed from this campaign earlier are restored as `pending`. `imported` counts only newly inserted rows. Unlike the single endpoint, email-only items are **not** matched against contacts in other campaigns. As with it, contacts added to an `active` campaign are not queued until the campaign is paused and activated again, and DNC lists and opt-outs are enforced at send time, not here. **Side effects.** Inserts the contacts, records their consent provenance (`import:api_bulk`, no evidence) and writes an audit entry. Nobody is contacted. **Idempotency.** Safe to retry: a repeated batch imports only phones that are not already in the campaign, so a retry after a timeout returns `imported: 0` for rows that landed the first time. **Webhook events.** `contact.created` for each new contact row (`{ contactId, campaignId, name, phoneNumber, email, whatsappNumber, status, source, createdAt }`, with `source` `api:bulk`); not sent when an existing contact is returned or a removed contact is restored; one event per inserted row. Delivered only to webhooks that name `contact.created` (the `"*"` wildcard does not include it). Also `audit.log_recorded` for webhooks subscribed to it. See [Webhooks](/webhooks). **Access** * **Required scope:** `write` (or `full`). * **Rate limit:** Contacts import — 5 requests/min per workspace, shared only by `/bulk`, `/upload-preview` and `/upload-confirm`, on top of the general API limit. See [Rate limits](/rate-limits). * **Plan:** The whole batch counts against the workspace-wide contact cap (Starter 500, Growth 2,000, Business 20,000). A batch that would go over it is refused entirely with 403 `BILLING_ERROR`; send a smaller batch. Reference: https://developer.jelliu.co/api-reference/contacts/post-campaigns-by-campaign-id-contacts-bulk ## Authentication - `Authorization` header (bearer token, required) — Workspace API key: `jl_` followed by 64 lowercase hex characters, created by the workspace owner in the dashboard (**Settings → API Keys**) and sent as `Authorization: Bearer jl_...`. The plaintext is shown once, at creation; Jelliu stores only a SHA-256 hash. A workspace can hold up to 25 active keys. | Scope | GET / HEAD | POST / PUT / PATCH / DELETE | Admin-only routes | | --- | --- | --- | --- | | `read` | Yes | No | No | | `write` | Yes | Yes | No | | `full` | Yes | Yes | Yes | Operations restricted to admins or owners reject keys without the `full` scope with `403`, and say so in their description. No key, whatever its scope, can mint or revoke API keys or rotate a webhook secret — that requires a signed-in owner session. A revoked key stops authenticating within about 10 seconds. See [Authentication](/authentication). ## Request ### Path parameters - `campaignId` (string, required) — UUID of the campaign that receives the contacts. An unknown, deleted or foreign campaign answers 404; a value that is not a UUID answers 400. ### Body (application/json) This endpoint expects an object. - `contacts` (list of object, required) — 1 to 5,000 contacts. Each needs at least one of `phoneNumber`, `email` or `whatsappNumber`. - `phoneNumber` (string, optional) — E.164 phone number with country code (`Must be E.164 format`). It is the dedup key in the campaign. Numbers shorter than 7 digits pass here but cannot be dialed and end as `invalid`. - `email` (string, optional) — Email address (`Invalid email`). Required for email campaigns. - `whatsappNumber` (string, optional) — E.164 WhatsApp number. Used as the dedup key when there is no `phoneNumber`. - `name` (string, optional) — Contact's name; the first word feeds `contact.first_name`. - `metadata` (map from string to string, optional) — Up to 20 keys matching `^[a-zA-Z0-9_-]+$`, string values up to 500 characters. The agent can read them, and tokens can use them as `contact.metadata.`. Card-like and 9-digit ID-like numbers are redacted before storage. - `crmExternalId` (string, optional) — Id of the matching record in an external CRM. - `crmProvider` (string, optional) — CRM the external id belongs to. ## Response ### 201 The batch was processed. - `data` (object, required) - `imported` (integer, required) — Newly inserted contacts. Duplicates, already existing and restored contacts are not counted. ## Errors ### 400 Bad Request Error The id is not a UUID, the body is invalid, or the campaign is completed/archived. - `error` (object, required) — The error object. Always has `code` and `message`. - `code` (string, required) — Stable machine-readable error code (for example `VALIDATION_FAILED`, `PAYLOAD_TOO_LARGE`, `UNAUTHORIZED`, `FORBIDDEN`, `NOT_FOUND`, `BILLING_ERROR`, `COMPLIANCE_BLOCKED`, `RATE_LIMIT_EXCEEDED`, `INTERNAL_ERROR`). Switch on this, not on `message`. See [Errors](/errors). - `message` (string, required) — Human-readable explanation. English or Spanish depending on the route; may change without notice. - `details` (object or list of object, optional) — Present on `VALIDATION_FAILED` only. Its shape depends on how the route validates: * a field map, either Zod's `flatten()` output (`{ "formErrors": [], "fieldErrors": { "name": ["..."] } }`) or just its `fieldErrors` part (`{ "name": ["..."] }`); * an issue list, where each issue has at least `path`, `message` and `code`. `path` is a dot-separated string on routes that let the schema throw, and an array of keys on routes that forward Zod's raw issues (those also carry Zod's extra issue fields); * for a rejected multipart upload (file in an unexpected field, too many files), a list with the upload error `code` (for example `LIMIT_UNEXPECTED_FILE`) and the `field` name. Absent when the value was rejected outside the route's own validation: a malformed id, number or date the database could not read, or a JSON body that does not parse. - Field map - `formErrors` (list of string, optional) - `fieldErrors` (map from string to list of string, optional) - `metadata` (map from string to any, optional) — Structured detail exposed for a small allowlist of codes only — for example `BILLING_ERROR` carries `limit`, `current` and `tier` (resource caps), `tier` alone (feature gates), or `tier` = `none` with `kind` = `subscription_required` when the workspace has no active subscription. See [Errors](/errors). ### 401 Unauthorized Error No usable credential. Either the `Authorization` header is missing or is not a well-formed `Bearer jl_…` key, or the key is unknown, revoked or expired. Do not retry with the same key. See [Authentication](/authentication#401-unauthorized). - `error` (object, required) — The error object. Always has `code` and `message`. - `code` (string, required) — Stable machine-readable error code (for example `VALIDATION_FAILED`, `PAYLOAD_TOO_LARGE`, `UNAUTHORIZED`, `FORBIDDEN`, `NOT_FOUND`, `BILLING_ERROR`, `COMPLIANCE_BLOCKED`, `RATE_LIMIT_EXCEEDED`, `INTERNAL_ERROR`). Switch on this, not on `message`. See [Errors](/errors). - `message` (string, required) — Human-readable explanation.

See [Errors](/errors). ### 403 Forbidden Error The batch would exceed the workspace contact cap (or the cap is already reached), or the API key lacks the `write` scope. - `error` (object, required) — The error object. Always has `code` and `message`. - `code` (string, required) — Stable machine-readable error code (for example `VALIDATION_FAILED`, `PAYLOAD_TOO_LARGE`, `UNAUTHORIZED`, `FORBIDDEN`, `NOT_FOUND`, `BILLING_ERROR`, `COMPLIANCE_BLOCKED`, `RATE_LIMIT_EXCEEDED`, `INTERNAL_ERROR`). Switch on this, not on `message`. See [Errors](/errors). - `message` (string, required) — Human-readable explanation.
