This endpoint allows you to update the properties of an existing processor. ### Path Parameters The ID of the processor to update. ### Body The new name for the processor. The new config to update the processor with. Must be `"EXTRACT"` for extraction processors. The base processor to use. For extractors, this is either `"extraction_performance"` or `"extraction_light"`. See the [base processor documentation](/changelog/overview) for more details. The version of the base processor to use (e.g. `"4.0.0"`). If this is provided, `baseProcessor` must be provided as well. See the [processor changelog](/changelog/overview) for available versions. The schema that defines the structure of data to extract from documents. One of `schema` or `fields` must be provided. We recommend using `schema` as `fields` is deprecated. See the [extraction processor schema documentation](/api-reference/guides/processor_configs20250421#extraction-processor-schema-json-schema) for more details. The schema that defines the structure of data to extract from documents. One of `schema` or `fields` must be provided. We recommend using `schema` as `fields` is deprecated. See the [extraction processor schema documentation](/api-reference/guides/processor_configs20250421#extraction-processor-configuration) for more details on using the `fields` shape. Unique identifier for the field. Human-readable name for the field. Type of the field. Supported values: * `string`: Text values * `number`: Numeric values * `currency`: Monetary values * `boolean`: True/false values * `date`: Date values * `array`: Lists of values (requires schema) * `enum`: Values from a predefined list (requires enum) * `object`: Nested structure (requires schema) * `signature`: Signature information Detailed description of the field, including expected content and format. Required when type is "array" or "object". Contains nested field definitions. Required when type is "enum". List of allowed values. The enum value. Description of the enum value. Custom rules to guide the extraction process in natural language. Advanced configuration options. Limit processing to a specific number of pages from the beginning of the document. Provide a hint about the document type (e.g. "invoice", "receipt", etc.). Define specific key terms or concepts relevant to the document type. Enable model reasoning insights in the extraction results. Enable advanced multimodal processing for better handling of visual elements. Enable citation information for extracted fields. Enable advanced parsing of figures and diagrams in the document. Options for controlling document chunking. Strategy for chunking the document. Supported values: * `standard`: Default chunking strategy * `semantic`: Content-aware chunking based on document structure Custom rules for semantic chunking in natural language. Number of pages per chunk. Strategy for selecting chunks. Supported values: * `intelligent`: AI-based selection * `confidence`: Select based on confidence score * `take_first`: Always use first chunk * `take_last`: Always use last chunk Must be `"CLASSIFY"` for classification processors. The base processor to use. For classifiers, must be `"classification_performance"` or `"classification_light"`. See the [base processor documentation](/changelog/overview) for more details. The version of the base processor to use (e.g. `"3.2.0"`). If this is provided, `baseProcessor` must be provided as well. See the [processor changelog](/changelog/overview) for available versions. Array of possible classifications for the document. Unique identifier for the classification. We recommend lowercase, underscore-separated format. Type identifier for the classification. Detailed description of the classification. Custom rules to guide the classification process in natural language. Advanced configuration options. Limit processing to a specific number of pages from the beginning of the document. The context to use for classification. Supported values: `default` `max` Enable advanced multimodal processing for better handling of visual elements during classification. Must be `"SPLITTER"` for splitter processors. The base processor to use. For splitters, this can currently only be `"splitter_performance"`. See the [base processor documentation](/changelog/overview) for more details. The version of the base processor to use (e.g. `"1.0.0"`). If this is provided, `baseProcessor` must be provided as well. See the [processor changelog](/changelog/overview) for available versions. Array of classifications that define the possible types of document sections. Unique identifier for the split classification. Type identifier for the split classification. Detailed description of the document section type. Custom rules to guide the document splitting process in natural language. Advanced configuration options. Limit processing to a specific number of pages from the beginning of the document. Method to use for splitting. Supported values: * `high_precision`: More accurate but potentially slower * `low_latency`: Faster but potentially less precise For Excel documents, split by worksheet. ### Response A true or false value indicating whether the processor was updated successfully or not. A DocumentProcessor object representing the updated processor. See the [DocumentProcessor object](/api-reference/objects/processor) for more details. ### Error Responses Will be `false` if the request failed. A description of the error that occurred. ```json Example Success Response theme={null} { "success": true, "processor": { "object": "document_processor", "id": "processor_1234", "name": "Updated Invoice Processor", "type": "EXTRACT", "createdAt": "2024-03-01T12:00:00Z", "updatedAt": "2024-03-01T13:00:00Z", "draftVersion": { "id": "dpv_4567", "version": "draft", "config": { "fields": [ { "id": "field_1234", "name": "invoice_number", "description": "The invoice number", "type": "string" } ] } } } } ```
