# REST API

Our Speckle Server offers both a GraphQL API and a REST API, for most of your queries the GQL API is probably best suited because of its flexibility and ease of use. When working with uploading and downloading objects, the REST API is preferred.

# Uploading and Downloading Objects

# Check if the server contains a list of objects

This method is useful for optimizing uploads, so that objects that are already in the stream are not uploaded for every commit.

URL: ${CANONICAL_URL}/api/diff/:streamId

Method: POST

Authentication: Token

Required permissions: Write permissions on the stream

Parameters:

  • objects (string): An array of object ids, serialized as a JSON string

Limits:

  • Recommended max number of objects to check: 1000

Output: A JSON representation of a dictionary, where the keys are the input object ids, and the values are boolean values (whether the server already has that object or not)

# Upload a batch of objects

URL: ${CANONICAL_URL}/objects/:streamId

Method: POST

Authentication: Token

Required permissions: Write permissions on the stream

Input: The batch to be inserted is sent as a multipart-encoded file content (filename is ignored) and is a JSON representation of an array of objects to be inserted

  • Example file content: [{"id": "9b2cdb21da092dbd3558a4bc55b2cf7e", "speckle_type": "Base", "totalChildrenCount": 0, "numbers": [0.04667752874618203, 0.16370857295385177, 0.1008153029515465]}])
  • The server accepts multiple batches as multiple files in the same call.
  • It's recommended to compress the batch with gzip and set the uploaded file content_type to application/gzip. Otherwise, set it to application/json

Limits:

  • Maximum size of each individual object: 10 MB (large objects can be split into multiple objects using chunkable properties and detachable properties)
  • Maximum size of each request: 50 MB hard limit

# Downloading a single object

URL: ${CANONICAL_URL}/objects/:streamId/:objectId/single

Method: GET

Authentication: Token

Required permissions: Read permissions on the stream

Output: The JSON representation of the object

# Downloading a list of objects

This method is useful when optimizing downloads: Get the root object without children, check the children ids in the local cache and then request only the new objects with this method.

URL: ${CANONICAL_URL}/api/getobjects/:streamId

Method: POST

Authentication: Token

Required permissions: Read permissions on the stream

Parameters:

  • objects (string): An array of object ids, serialized as a JSON string

Headers:

  • Accept: either text/plain or application/json

Limits:

  • Recommended max number of objects to download with 1 request: 1000

Output: The requested objects. The formatting is based on the Accept HTTP Request header

  • If Accept is text/plain, each line of the output contains 1 object in the format: {object_id}\t{object_content}
  • If Accept is application/json, the output is a JSON representation of an array of objects.

# Downloading an object and all its children

URL: ${CANONICAL_URL}/objects/:streamId/:objectId

Method: GET

Authentication: Token

Required permissions: Read permissions on the stream

Headers:

  • Accept: either text/plain or application/json

Output: The requested object and its children. The formatting is based on the Accept HTTP Request header

  • If Accept is text/plain, each line of the output contains 1 object in the format: {object_id}\t{object_content}
  • If Accept is application/json, the output is a JSON representation of an array of objects.
