Instagram started providing access to its Content Publishing API publicly. The API supports scheduling and publishing single photos or single videos for Instagram business accounts.
Photo Requirements for automatic publishing:
Maximum file size: 8 MB
Minimum width: 320 px
Maximum width: 1440 px
Aspect ratio: Must be within a 4:5 (portrait) to 1.91:1 (landscape) range
Height: Varies, depending on width and aspect ratio
Formats: JPG, JPEG
Find official detailed instructions from FB here.

Here is a little help:
Note: Requirements for photos published manually are given by the native Instagram application. 💡
