Twitter crossposter

@robi said in Twitter crossposter:
I'd like to connect Insta posting to Twitter posting and not necessarily from the same account(s)
I don't use Instagram but ironically just found one of my 'persons of interest' does, and mostly tweets links to Insta posts. So you have to follow them to see content. So I may look into this.
Brief research shows you can use Bibliogram to get an RSS feed of Instagram posts from an Insta account. Based on that, it seems at first glance that it is possible to use similar workflow to my Mastodon2Twitter to achieve that.
I tried briefly to self-host Bibliogram but installation failed, so as Instagram is low usage for me, I'm just using a hosted Bibliogram (https://bibliogram.snopyta.org/) to give me the RSS feed.
EDIT : just seen Bibliogram is a supported app on Yunohost. I don't have a Yunohost server .... yet !
-
@timconsidine Beautiful, nice find on bibliogram.
I was looking at other such services and Nitter showed up, with a bit more understanding of why it exists as described here:
https://nitter.1d4.us/aboutThis also means that if you replace your Twitter node with a Nitter node, you'll likely have a better experience posting to Twitter. (no rate limits of dev account required)

oooo, didn't know I could do that !
I also noticed RSS-Bridge supports an Instagram feed, but haven't played with it yet.
-
@timconsidine I may be wrong as so far it seems as a read-only config, not sure if one can post to Twitter as well.
-
@robi I don't think you can post via Nitter, it is has no login, just read-only.
But your post made me think because as you say, the dev accounts have rate limits.
Limits are not so bad, but they're there, and for some use cases, could be a problem, e.g. analysis and "tweet intelligence".
My current n8n is great for posting, and I won't hit rate limits.
But for other use, a lot of tweet fetching might.
That's where Nitter can come into play. -
@timconsidine https://github.com/FriendsOfREDAXO/feeds might be good intermediary step so you get nice RSS feeds for N8N.
-
@timconsidine Hey, I'm trying to achieve a similar scenario but I'm not getting far, would you by any chance share your n8n workflow ?
-
@rmdes here is my n8n workflow for taking an RSS feed from a mastodon user and posting that to twitter
It can sure be made more sophisticated but it works in basic form
Main point is that it requires a Twitter OAuth login, which is usually (always?) obtained by having a Twitter API registration which gives you the credentials needed to be input in your n8n.
It is not your normal Twitter login.Getting a Twitter API account is not difficult but it's not entirely straight forward. They seem to randomly accept/reject for unclear reasons. But if you have one already or are patient to go through the process, you should be good to go.
Cam't seem to attach a file so you may have to copy/paste this into a .json file and then import that into your new n8n workflow.

@timconsidine hey there, thanks a lot for the recipe, going to test this out !!
- can you explain why the Twitter node is not connected to anything ?
- also can you explain what the 5 min function is doing ?
I'm asking because even though I have setup everything, (have my own twitter credentials ready and obviously changed the RSS source but I see no posts being created, even though the recipe clearly fetch my RSS feed and at the end of the workflow the twitter node "see" the content of the last theoretical tweet the workflow should have made...but nothing get's out on twitter..
No errors on any of the workflow, it all seems to be great, but no output ?!
-
The Twitter node is not connected to anything as output, because it is the end of the process.
Are you saying it is not connected on input side when you import the workflow ? But I think it is because our screenshot some incoming values.The 5min function was was simply to filter out posts on Mastodon made >5 mins ago, so that the workflow did not attempt to post "old" posts to Twitter. My understanding is that Twitter would not detect a duplicate tweet (although it does detect duplicate RTs). So the function just takes Mastodon posts from <5 mins age. This is also related to the cron running the workflow every 5 mins.
Of course you can adjust these values or remove them, but you might get duplicate tweets.
Twitter should give an error if there is a problem, which you can see in the n8n step. Nothing showing there ?
-
@timconsidine No no the input is connected just fine, maybe it's just me I had not seen a workflow like this before and it feels weird that nothing goes published..not even sure where to look since I don't have any errors, all executions are success...
-
@timconsidine by the way, twitter does even more, it detect duplicates tweets also based on content, title + link, if the attempt is made to tweet an item that was already tweeted via the application, the twitter api return an "duplicate tweet" error (that's with my previous python based RSS to twitter experiment) when the duplicate tweet is detected, twitter simply reject the second attempt at tweeting the same thing twice.
I think I will have to increase the 5 min because, provided I don't have duplicates I don't mind going back 1h ago to tweet items, I was under the impression that maybe one of the reason it does not tweet the output is maybe because the time span is too short ?
-
@timconsidine I increased the time to 1800.000, so 30 minutes, but I don't see any difference, wondering what's happening
edit : I have 400+ json item that each part of the workflow can fetch, see, but nothing gets out... -
@timconsidine When I do so I get this error on the HTTP Request node when I execute the workflow :
The "url" argument must be of type string. Received undefined
{
"status": "rejected",
"reason": {
"code": "ERR_INVALID_ARG_TYPE",
"cause": {
"code": "ERR_INVALID_ARG_TYPE"
},
"error": {
"code": "ERR_INVALID_ARG_TYPE"
},
"options": {
}
}
}Actually I don't understand what this Node is doing, can't I send the data directly to twitter after the IF ?
-
@rmdes yes you can send to Twitter node after the IF node providing the tweet is text only. The HTTP node is used to capture any images in the Mastodon tweet and attach them (as binary data I think)
You may just need to "re-map" the HTTP node links from IF node, or re-map the links in the Twitter node to the HTTP output.
I usually step through each node from the start (using that node's run icon, not the whole workflow run icon), and in each subsequent node, check the Input parameters to select the incoming data and map to the node's parameters.
Then I do an end-to-end test.
My workflow provides the general schema, but I had problems on importing other workflows (different use cases). I just deleted each imported node one-by-one and recreated the mode manually, linking to the previous node as explained above.
-
@timconsidine Thanks & sorry for late reply, I managed to get it working, but I'm not happy with the result in my use case, in fact I'm not happy with N8, the main issue being missing key features to validate their "no code" approach, I think some key elements are missing that render any attempt to use n8 for automation-publishing a real P in the A..
- I tried dozens of implementations, taking on recipe from others to rebuild my own and after several months of testing, I see duplicates, n8 stuck in loop publishing over and over the same stuff, I may be doing something wrong but the moment you add complexity to the recipe, let's say : add some RSS feeds feeding the same output, the situation becomes a mess.
