How can I generate invite links to Trello board

[devmanProjectsTgBot]

Hi, Im building an chat-bot app, and I use your Trello API, to create organizations and boards, I want to invite people to these boards sending them invite links, but I couldnt find a way to generate one.
I only found API docs about inviting people with email, but it isnt really what I need

I also fumbled around Trello web site and found out that this API hand exists, though there is nothing about it in docs:
https://trello.com/1/boards/{board_id}/invitationSecret

If we explore request, that is sent from Trello web-site, we can see that there are 2 things in request’s payload
“token” - as I supose it is user_id/session_id, if we make requests from outside this is only an API token
“type”: “normal:” -I didn’t really understand what it is.

So if Im using a REST API to send this request I configure my payload as

query = {
    'key': my_trello_api_key,
    'token': my_trello_api_token,
    'type': 'normal'    
}

but it always returns 401 ‘unauthorized permission requested’

Also found this topic, but as I suppose Adriana is missing the fact that server is blocking request to this url (or am I 'm being stupid and missing something obvious )

Board Invite Link?

Hi, I’m Adriana and I’m an engineer at Trello. I want to make sure I’m understanding you correctly. You want the API to return the link to share the board? May I ask to what end are you using this link? Otherwise, if you are just using the link to add people to the board, you might consider using the API to add a user via email. Or, if the user is already a Trello user, you can also add a user via their member id.

hey, adriana here.

i don’t see a request payload like that in my network when i open the share modal. the web client should make a request to https://trello.com/1/boards/:idBoard/invitationSecret, as you’ve identified. however, there is no key and token in the parameters of that request.

i believe that you need the cookie from your browser to generate the invitation secret, and it’s set in the request headers, not as a parameter. that request should return a payload like {secret: '', type: 'normal}. that secret is referenced in the previous post, and can be sent to https://trello.com/invite/b/:idBoard/:secret to redirect to the ‘shared board’ page.

so, in sum:

• if you have access to your cookie, you make a request to https://trello.com/1/boards/:idBoard/invitationSecret to generate a secret, using the cookie in the headers and not as a request parameter/body
• use the returned secret to send a generated invite link like https://trello.com/invite/b/:idBoard/:secret, which will redirect to the “[user] has shared this board” page

let me know if that works for your situation.

Thats kinda worked for GET request, I just copy-pasted all ‘cookie’ header from direct request to …/invitationSecret from browser and GET request to API returned a secret, but it still doesnt works with POST, witch as I see in browser, creates secrets

When i click Create link it sends POST request to invitationSecret, to create one and then GET to actually… get it and push it into copy link thing

so if I want to send invites automatically, I need to do both POST & GET
UPD
Actually It is doable with only POST as it returns the same Json as GET, so I just need to make 1 POST request and get secret from it’s response
