Is there a way to accept a certain trade offer through message with its offerid?

[TextDynasty]

Hi, so I wrote a few codes to my bot to make it send me a message with offer id included once there's a need for the background check. But I don't know how or is there a way to make it accept the trade offer through providing the trade offer id to the bot.

const parseAdminMessage = (message) =>{
 if (message.substring(0,8) == '!accept '){
    var offerid = message.substring(8);
    console.log(offerid); //It can show the correct offerid here but i dont know how to make it accept the trade by the offerid
}

//This is what I used to accept normal trade offer with the offer status

const acceptTradeOffer = (offer) => {
    offer.accept(false, function(error, status) {
        if (error) {
            logger.error(`| OFFER RECEIVED |: ID#${offer.id} has failed trying to accept it. Reason: Offer is no longer valid.`);
            return 'Badass';
        } else if (status === 'pending') {
            logger.info(`| OFFER NEEDS CONFIRM | : ID#${offer.id} is accepted but needs confirmation`);
            var confCount = 0;
            function confirm(idSecret, idOffer) {
                community.acceptConfirmationForObject(idSecret, idOffer, function(error) {
                    confCount++
                    if (error) {
                        if (confCount < 4) {
                            confirm(idSecret, idOffer);
                        } else {
                          logger.error(error);
                            logger.fail(`| OFFER RECEIVED | : ID#${offer.id} has failed trying to confirm it. Reason: Offer is no longer valid.`);
                            return 'done';
                        }
                    } else {
                        return 'done';
                    }
                });
            }
            confirm(config.identity_secret, offer.id);
        } else {
            return 'done';
        }
    });
}

You'll need to retrieve the offer first.

You'll need to retrieve the offer first.

 if (message.substring(0,8) == '!accept '){
    var offerid = message.substring(8);
    manager.getOffer(offerid, function(offer) {
        offer.accept(false, function(error, status) {
            if (error) {
                logger.error(`| OFFER RECEIVED |: ID#${offer.id} has failed trying to accept it. Reason: Offer is no longer valid.`);
                return;
            } else if (status === 'pending') {
                logger.info(`| OFFER NEEDS CONFIRM | : ID#${offer.id} is accepted but needs confirmation`);
                community.acceptConfirmationForObject(config.identity_secret, offer.id);
            }
        })
    })
  }

Is this what you mean by getOffer?

 

It has this error

        offer.accept(false, function(error, status) {
              ^

Solved.  Thanks McKay

Please post your solution for others in the future.

 

In this case, the problem was that the first argument to the callback should be err, not offer.
