Endpoint Details

👍
Added in Dash Platform 0.20.0
Dash Platform 0.20.0 introduced proofs to Platform gRPC endpoints so the data returned for a request can be verified as being valid. Full support is not yet available in the JavaScript client, but can be used via the low level via dapi-grpc library. Additional information about proofs is available on the Platform Proofs page.
This version also added some additional metadata to responses:

height: the last committed platform chain height

coreChainLockedHeight: height of the most recent ChainLock on the core chain

broadcastStateTransition

📘
Updated in Dash Platform 0.18.0
Since Dash Platform 0.18.0 broadcastStateTransition returns once the state transition has been accepted into the mempool instead of waiting until it is confirmed.
Note: The waitForStateTransitionResult endpoint should be used in conjunction with this one for instances where proof of block confirmation is required.

Broadcasts a state transition to the platform via DAPI to make a change to layer 2 data.

Returns: Nothing or error
Parameters:

Name	Type	Required	Description
`state_transition`	Bytes (Base64)	Yes	A state transition

getIdentitiesByPublicKeyHashes

Returns: Identity information associated with the provided public key hashes
Parameters:

Name	Type	Required	Description
`public_key_hashes`	Bytes	Yes	Public key hashes (double-sha256) of identity public keys
`prove`	Boolean	No	Set to `true` to receive a proof that contains the requested identities

getDocuments

Returns: Document information for the requested document(s)
Parameters:

🚧

Parameter constraints

The where, order_by, limit, start_at, and start_after parameters must comply with the limits defined on the Query Syntax page.
Additionally, note that where and order_by must be CBOR encoded.

Name	Type	Required	Description
`data_contract_id`	Bytes	Yes	A data contract `id`
`document_type`	String	Yes	A document type defined by the data contract (e.g. `preorder` or `domain` for the DPNS contract)
`where` *	Bytes	No	Where clause to filter the results (must be CBOR encoded)
`order_by` *	Bytes	No	Sort records by the field(s) provided (must be CBOR encoded)
`limit`	Integer	No	Maximum number of results to return
----------
One of the following:
`start_at`	Integer	No	Return records beginning with the index provided
`start_after`	Integer	No	Return records beginning after the index provided
----------
`prove`	Boolean	No	Set to `true` to receive a proof that contains the requested document(s)

🚧
Note: When requesting proofs, the data requested will be encoded as part of the proof in the response. See the Platform Proofs page for details on decoding the data.
