We have the following topology in Canton: We have single domain named “MYDOMAIN” which contains two participants nodes “A” and “B”. The “A” ledger node uses port “10001” and “B” uses “11001” port. We have created one DAML A-Certificate in “A” node and then B-Certificate in a “B” node using JSON Api service. Is there way to share/use/makevisible certificates created in “A” participants node to “B” participant node using JSON API service? ---

Hi @Grigor, welcome to the DAML community forum. The JSON API shows active contracts. on which the requesting party, specified as part of the JWT, is a stakeholder. _Parties_ here are different to nodes, but in Canton each note also comes with its own party, called something like `participant1::somehash` by default. So if you have two parties `A::somehash` and `B::anotherhash` hosted on nodes A, and B, respectively, A can make a contract visible to B by adding `B::anotherhash` as an [observer](https://docs.daml.com/daml/reference/templates.html#observers) to that contract. ---

Thanks for quick response @bernhard Here is my case: // A and B are participants A.domains.connect\_local(MYDOMAIN) B.domains.connect\_local(MYDOMAIN) Alice is a party in A participants node, and Bob is the party in B node. Alice created contractID with JSON API in A participant node, and BOB need to accept it, when I am trying to refer that contract ID created in A node json API gives an error: "io.grpc.StatusRuntimeException: INVALID\_ARGUMENT: Command interpretation error in LF-DAMLe: dependency error: couldn’t find contract AbsoluteContractId So I am thinking what is the way to share that contractID created in A participants node in B. ---

Hi @Grigor, as @Bernhard mentioned, the way to share a contract with another party on the ledger is via the `observer` field of the contract. Would it be possible for you to share the DAML code of the `Certificate` contract?
