I did some digging (becuase I wanted to know how to) and i found out that the config is a GraphQL JSON string. The whole mutation will look like this:
mutation {
create_webhook ( board_id: 111111, url: “https://a/webhook/url”, event: change_specific_column_value config:“{"columnId":"status1"}”) {
id
board_id
}
}
where status1 is the column that you want to be notified by.
note: the Inner " require a \\ in front of them.
Hi @ptsgJason, Jason
You are the champ! Works like a charm. Just curious to know where you got the info from as I was unable to find any documentation on this. Especially the lack of the comma between the WebhookType and the config argument is a really good find 🙂
This saves a lot of back and forth traffic.
For those who are adding webhooks to a board through the API (e.g. in a subscribe event from a custom trigger) take care: lot of escaping to do!
I use a function like below to inset any type of webhook to a board and returns the trigger Id. (forgive the formatting, not the best editor here 🙂
static async createWebhook(token, boardId, webhookUrl, webhookType) {
try {
const mondayClient = initMondayClient();
mondayClient.setToken(token);
const query =
mutation create_webhook($boardId: Int!, $webhookUrl: String!) { create_webhook(board_id: $boardId, url: $webhookUrl, event: +
webhookType +
) { id } } ;
const variables = { boardId, webhookUrl };
const response = await mondayClient.api(query, { variables });
return response.data.create_webhook.id;
} catch (err) {
console.log(err);
}
}
This function is called like this for an add_item webhook, with a token, a boardId, a webhookUrl (I my specific case I needed the host part dynamic) and a webhookType.
const triggerHooks = await mondayService.createWebhook(
token,
boardId,
“https://” + req.headers.host + “/vote-to-group/webhookaction”,
“change_column_value”
);
Now, for the change_specific_column_value webhook you can still use the same function but take care of all the escaping done for the last argument (webhookType). All the \\ characters in the last argument are really double-backslashes (\\\\) but lost in this code editor. At least in VSCode you need to escape the escape character 🙂
const triggerHooks = await mondayService.createWebhook(
token,
boardId,
“https://” + req.headers.host + “/vote-to-group/webhookaction”,
‘change_specific_column_value config: “{\\“columnId\\”:\\”’ + columnId + ‘\\“}”’
);
Many thanks to @ptsgJason for this find and happy webhooking 🙂
Hey @basdebruin
Sorry for our delay in handling this! I’m glad to see this is working correctly now!
Let us know if we can help with anything else.

@ptsgJason, when you states “I did some digging”; how did you do this ? 😃
