I have a list that has a look-up column into another list. Ex: B list has a look-up column called 'navB' that is a look-up into a column in list A. The name of that column in list A is called 'navA'.

When I look at the api, I see an ID called 'navBId'.

I try to expand it like this but it doesn't work


I get an error when I do this.

What am I doing wrong? Thanks

As @Dylan said, when using $expand endpoint you need to mention the column name from List B in $expand and then you can select the column from List A in $select query like below:


Adding to this answer,

You cannot expand and select all the columns from List A as lookup columns does not support all the column types.

Supported Column Types:

  • Single line of text
  • Choice (single value)
  • Number
  • Currency
  • Date and Time
  • Lookup (single value)
  • Person or Group (single value)

Unsupported Column Types:

  • Multiple lines of text
  • Choice (multi-valued)
  • Calculated
  • Hyperlink or Picture
  • Custom Columns
  • Lookup (multi-valued)
  • Person or Group (multi-valued)
  • Yes/No
