Links and validation errors

Short links

If your post contains a URL, UseNadia can shorten it so clicks are trackable. The behaviour is a setting, not a per-post decision:

Preference	What happens
Ask every time	You are prompted before saving
Always shortlink	URLs are shortened silently
Never shortlink	URLs are left alone

Set it in Settings, see Settings.

When prompted, the wording is:

Do you want to shortlink the URLs? it will let you get statistics over clicks

Shortened links produce a click table in the post’s statistics.

Note

A link in an Instagram caption is not clickable anyway. If the point of the link is that someone follows it, a comment → DM automation sends it as a button in a direct message instead.

Validation

UseNadia validates a post against every selected channel before saving. If any channel fails, nothing is saved, and the composer takes you to the block at fault with the error shown — by switching to that channel’s tab on a desktop, by scrolling on a phone.

The same validation runs again on the server when you submit, so you cannot bypass it by editing the request. It is also the same validation the Public API and the agent go through.

What usually fails

Error	Cause
Your post should have at least one character or one image	An empty post
post is too long	Over the character limit for that platform, see Writing the post
Should have at least one media	Instagram with no attachment
Trial Reels can only have one video / must be a video	A trial reel with anything other than one video
No video / images selected	TikTok with no attachment
Only pictures are supported when selecting multiple items	TikTok with several attachments, one of which is a video
You need one media / Item must be a video	YouTube with anything other than exactly one MP4
Missing setting	A required per-platform field is empty

Fixing them

For length, detach the offending channel and write a shorter version rather than cutting the text everywhere. See Global vs per-channel.

For media, check the platform’s rules first, since the constraint usually comes from the platform rather than from UseNadia. See Posting rules by platform and Images and video.

For required settings, open the Settings band at the bottom of the composer and fill them in. Required fields are the ones the platform refuses posts without, so there is no way around them.
