How to submit an Offer to a contract using PurseInvitationSpec

[dillu24]

Let's say that I have a basic hello world contract which invites specific users to print arguments. I managed to deposit a printArgs invitation to my wallet and now I want to submit an offer to my contract programatically or using a shell script, passing custom offerArgs inside my offer. Am I on the right track? I am particularly not sure what instance should be.

let templateOffer = {
    invitationSpec: {
      source: "purse",
      description: "printArgs",
      instance: <not-sure-what-this-should-be>
    },
    offerArgs: "Hello World",
    id: Number(Date.now()),
    proposal: {},
};

Do us a favor? take a look at Specifying Offers, especially Marshalling Amounts and Instances and give us some feedback?

We aim to do some work on it to update it w.r.t. ui-kit. But meanwhile, if you like, you can take a look at what we have.

a detail:

    offerArgs: "Hello World",

I think offerArgs has to be an {...} object.

Will have a look at the resources, thanks for that.

FYI I had managed to make this work as follows:

let templateOffer = {
    invitationSpec: {
      source: "purse",
      description: "printArgs",
      instance: fromBoard.convertSlotToVal('board063107', "Alleged: InstanceHandle"),
    },
    offerArgs: harden({test: "Hello World"}),
    id: Number(Date.now()),
    proposal: {},
};

      instance: fromBoard.convertSlotToVal('board063107', "Alleged: InstanceHandle"),

bingo! well done.
