Update an existing graph with new documents.

This endpoint processes additional documents based on the original graph filters
and/or new filters/document IDs, extracts entities and relationships, and
updates the graph with new information.

Args:
    name: Name of the graph to update
    request: UpdateGraphRequest containing:
        - additional_filters: Optional additional metadata filters to determine which new documents to include
        - additional_documents: Optional list of additional document IDs to include
        - prompt_overrides: Optional customizations for entity extraction and resolution prompts
        - folder_name: Optional folder to scope the operation to
        - end_user_id: Optional end-user ID to scope the operation to
    auth: Authentication context

Returns:
    Graph: The updated graph object

Update Graph

Represents an entity in a knowledge graph

Chunk Sources

Document Ids

Label

Properties

Type

Entity

Example entity for guiding entity extraction.

Used to provide domain-specific examples to the LLM of what entities to extract.
These examples help steer the extraction process toward entities relevant to your domain.

The entity label (e.g., 'John Doe', 'Apple Inc.')

Optional properties of the entity (e.g., {'role': 'CEO', 'age': 42})

The entity type (e.g., 'PERSON', 'ORGANIZATION', 'PRODUCT')

EntityExtractionExample

Configuration for customizing entity extraction prompts.

This allows you to override both the prompt template used for entity extraction
and provide domain-specific examples of entities to be extracted.

If only examples are provided (without a prompt_template), they will be
incorporated into the default prompt. If only prompt_template is provided,
it will be used with default examples (if any).

Required placeholders:
- {content}: Will be replaced with the text to analyze for entity extraction
- {examples}: Will be replaced with formatted examples of entities to extract

Example prompt template:
```
Extract entities from the following text. Look for entities similar to these examples:

{examples}

Text to analyze:
{content}

Extracted entities (in JSON format):
```

Examples of entities to extract, used to guide the LLM toward domain-specific entity types and patterns.

Examples

Custom prompt template, MUST include both {content} and {examples} placeholders. The {content} placeholder will be replaced with the text to analyze, and {examples} will be replaced with formatted examples.

Prompt Template

EntityExtractionPromptOverride

Example for entity resolution, showing how variants should be grouped.

Entity resolution is the process of identifying when different references
(variants) in text refer to the same real-world entity. These examples
help the LLM understand domain-specific patterns for resolving entities.

The canonical (standard/preferred) form of the entity

Canonical

List of variant forms that should resolve to the canonical form

Variants

EntityResolutionExample

Configuration for customizing entity resolution prompts.

Entity resolution identifies and groups variant forms of the same entity.
This override allows you to customize how this process works by providing
a custom prompt template and/or domain-specific examples.

If only examples are provided (without a prompt_template), they will be
incorporated into the default prompt. If only prompt_template is provided,
it will be used with default examples (if any).

Required placeholders:
- {entities_str}: Will be replaced with the extracted entities
- {examples_json}: Will be replaced with JSON-formatted examples of entity resolution groups

Example prompt template:
```
I have extracted the following entities:

{entities_str}

Below are examples of how different entity references can be grouped together:

{examples_json}

Group the above entities by resolving which mentions refer to the same entity.
Return the results in JSON format.
```

Examples of entity resolution groups showing how variants of the same entity should be resolved to their canonical forms. This is particularly useful for domain-specific terminology, abbreviations, and naming conventions.

Custom prompt template that MUST include both {entities_str} and {examples_json} placeholders. The {entities_str} placeholder will be replaced with the extracted entities, and {examples_json} will be replaced with JSON-formatted examples of entity resolution groups.

EntityResolutionPromptOverride

Container for graph-related prompt overrides.

Use this class when customizing prompts for graph operations like
create_graph() and update_graph(), which only support entity extraction
and entity resolution customizations.

This class enforces that only graph-relevant override types are used.

Overrides for entity extraction prompts - controls how entities are identified in text during graph operations

Overrides for entity resolution prompts - controls how variant forms are grouped during graph operations

GraphPromptOverrides

Represents a relationship between entities in a knowledge graph

    apply_to_existing: Whether to apply rules to existing documents in the folder

Returns:
    Success status with processing results

Set Folder Rule

Delete *all* resources associated with *app_name* for the calling user.

This removes:
• All documents linked to the application's ``app_id`` (includes chunks & S3
  via existing delete_document flow).
• The *apps* table entry.
• The reference in *user_limits.app_ids*.

Delete Cloud App

Generate a cloud URI for *request.app_id* owned by the calling user.

The *user_id* is derived from the bearer token.  The caller can therefore
not create applications for *other* users unless their token carries the
``admin`` permission (mirroring the community behaviour).

Create App

Provision a **brand-new** Neon database for *request.app_name*.

The caller must be authenticated to the dedicated Morphik instance.  The
authenticated user (represented by the JWT's *user_id*) becomes the owner
of the provisioned app.

Create App Route

Destroy the Neon project and metadata associated with *app_name*.

Only the owner of the application (identified via *auth.user_id*) may
perform this destructive action.

Delete App Route

Checks the current authentication status for the given connector type.

Get Auth Status For Connector

Return the provider's *authorization_url* for the given connector.

The method mirrors the logic of the `/auth/initiate` endpoint but sends a
JSON payload instead of a redirect so that browsers can stay on the same
origin until they intentionally navigate away.

Get Initiate Auth Url

Handles the OAuth 2.0 callback from the authentication provider.
Validates state, finalizes authentication, and stores credentials.

Connector Oauth Callback

Lists files and folders from the specified connector.

List Files For Connector

Downloads a file from the connector and ingests it into Morphik via DocumentService.

Ingest File From Connector

Disconnects the user from the specified connector by removing stored credentials.
