# Upsert multiple articles

POST https://example.ada.support/api/v2/knowledge/bulk/articles/
Content-Type: application/json

Upsert an array of knowledge articles

This endpoint will create or update articles based on the unique `id` field of each article. If an article with the same `id` already exists, it will be updated. Otherwise, a new article will be created.

**Limits:**

* The maximum size of a request payload is 10MB
* The maximum size of an article is 100KB
* The maximum number of articles is 50,000 by default. Higher limits are available for eligible plans — contact your Ada team.

**Behavior at the article limit:**
Requests that only update existing articles (every `id` in the request already exists) continue to succeed even when your knowledge base is at its article limit. A request that introduces any new article `id` while at the limit is rejected as a whole with a `400` response. The error message is `Maximum article limit of {N} exceeded`, where `{N}` is your article limit, and the error details include a `code` of `knowledge.articles.total_exceeded`, the list of `new_article_ids` that triggered the rejection (capped at the first 100), and the total `new_article_count`. Use these fields to separate new articles from update-only batches, which can still be submitted.

## Response

### 200

Articles upserted

- `list of KnowledgeArticleUpsertResponse`

## Errors

### 400 Bad Request Error

Bad Request

- `errors` (list of ErrorsErrorsItems, required) — A list of errors

### 401 Unauthorized Error

Unauthorized

- `errors` (list of ErrorsErrorsItems, required) — A list of errors

### 429 Too Many Requests Error

Too Many Requests

- `errors` (list of ErrorsErrorsItems, required) — A list of errors

### 500 Internal Server Error

Internal Server Error

- `errors` (list of ErrorsErrorsItems, required) — A list of errors

## Types

### KnowledgeArticleUpsertRequest

- `id` (string, required) — A unique identifier for the article
- `name` (string, required) — The name or title of the article
- `content` (string, required) — The content of the article in markdown format
- `knowledge_source_id` (string, required) — The id of the `knowledge_source` the article belongs to
- `url` (string, optional, nullable) — The url of the article
- `tag_ids` (list of string, optional) — A list of ids for the tags associated with the article
- `language` (string, optional) — The IETF BCP 47 language code for the article, defaults to `en`
- `external_created` (string, optional, nullable) — The date the article was created in the source system
- `external_updated` (string, optional, nullable) — The date the article was last updated in the source system
- `enabled` (boolean, optional) — Whether the article should be referenced during response generation, defaults to `true`
- `metadata` (KnowledgeArticleUpsertRequestMetadata, optional, nullable) — A dictionary of arbitrary key,value pairs. This data is not used by Ada, but can be used by the client to store additional information about the article.
- `availability_rules` (AvailabilityRule, optional, nullable) — Availability rule controlling which articles the AI Agent can access during a conversation. Send a rule object to attach or replace a rule, `null` to detach an existing rule, or omit the field to leave any existing rule unchanged. A rule may contain at most 1000 conditions in total. See [Availability rules](/reference/introduction/availability-rules) for the full schema and examples.

### KnowledgeArticleUpsertResponse

- `id` (string, required) — A unique identifier for the article
- `success` (boolean, optional) — Whether the article was successfully created/updated
- `created` (boolean, optional) — `True` if a new article was created, `false` if an existing article was updated

### ErrorsErrorsItems

- `type` (string, required) — The error type
- `message` (string, required) — The error message
- `details` (string, optional, nullable) — Extra information about the error

### KnowledgeArticleUpsertRequestMetadata

A dictionary of arbitrary key,value pairs. This data is not used by Ada, but can be used by the client to store additional information about the article.

### AvailabilityRule

A two-level tree of conditions that determines availability based on variable values during a conversation. The root group has a `match` combinator and a list of conditions or condition groups. A rule may contain at most 1000 conditions in total, counting every condition across the root and all nested condition groups.

- `match` (enum, required) — Whether all conditions must pass (`all`) or any one condition must pass (`any`).
  - Allowed values: `all`, `any`
- `conditions` (list of AvailabilityRuleConditionsItems, required) — List of conditions or condition groups. Must contain at least one entry. Each entry is either a `Condition` object (with `variable`, `operator`, and optional `value`) or a `ConditionGroup` object (with its own `match` and nested `conditions` list).

### AvailabilityRuleConditionsItems

### AvailabilityRuleCondition

A single condition comparing a variable to a value.

- `variable` (AvailabilityRuleConditionVariable, required) — The variable to test, referenced by `id`. Look up the ids for your Agent through the variables endpoint. Not every variable can be used in a rule; referencing one that can't returns a `400`.
- `operator` (enum, required) — The comparison operator. Unary operators (`is_set`, `is_not_set`) must not include a `value` field.
  - Allowed values: `equals`, `does_not_equal`, `greater_than`, `less_than`, `starts_with`, `ends_with`, `contains`, `does_not_contain`, `is_set`, `is_not_set`
- `value` (AvailabilityRuleConditionValue, optional) — The value to compare against. Omit for unary operators (`is_set`, `is_not_set`).
- `case_sensitive` (boolean, optional) — Whether the comparison is case-sensitive. Defaults to `false`. Only meaningful for the equality (`equals`, `does_not_equal`) and string (`starts_with`, `ends_with`, `contains`, `does_not_contain`) operators. Omitted from responses when `false`.

### AvailabilityRuleConditionGroup

A nested group of conditions inside a rule's top-level `conditions` list. Condition groups may contain only `Condition` objects — further nesting is not supported.

- `match` (enum, required) — Whether all conditions must pass (`all`) or any one condition must pass (`any`).
  - Allowed values: `all`, `any`
- `conditions` (list of AvailabilityRuleCondition, required) — List of conditions inside this condition group. Must contain at least one entry.

### AvailabilityRuleConditionVariable

The variable to test, referenced by `id`. Look up the ids for your Agent through the variables endpoint. Not every variable can be used in a rule; referencing one that can't returns a `400`.

- `id` (string, required) — The id of the variable.

### AvailabilityRuleConditionValue

The value to compare against. Omit for unary operators (`is_set`, `is_not_set`).
