## Add a New Link to the Issue

Link the current issue to another issue.

Required fields: `id` - the database ID of the issue you're linking to the current one.

Put the ID of the link type into the URL as `linkID`. To get the list of available link types and choose the one you need, send a GET request to `/api/issueLinkTypes?fields=id,name`. For details, see [Read a List of IssueLinkTypes](https://www.jetbrains.com.cn/en-us/help/youtrack/devportal/resource-api-issueLinkTypes.html).

If the chosen link type is directed, append a direction marker to the ID of the link type:

* For an outward link, append the `s` marker. Example: `80-1s`.

* For an inward link, append the `t` marker. Example: `80-1t`.

If the chosen link type is not directed, use the link type ID without markers. Example: `80-1`.
