I am trying to use the extensibility API method, addLine. the method works fine, However I would like to insert data into a custom field when doing it and cant seem to make it work. I set up a custom transaction item option field called custcol_subscription_frequency I also tried transaction line fields, checked the applies to boxes for sale and web... Then I am trying to run the following code which I am not even sure is correct any more...

container.getComponent('Cart').addLine({

line: {

quantity: '2',

item: {

internalid: '840'

},

options: [

{

cartOptionId: 'custcol_subsscription_frequency',

value: "2"

}

]

}

}).then(data => {

console.log('Item added', data);

Backbone.history.navigate('/cart', {trigger: true});

}).fail(error => {

console.error('There was an error adding the item', error);

alert('There was an error adding the item, see console for details.');

});

When I run this code block the item is added to the cart, but the option is not set. any help is much appreciated!

Is custcol_subsscription_frequency spelled correctly?

LOL Sorry, it is correct, I think just in the last test I fat fingered and thats what I coppied

OK, well other than that the only obvious things are that quantities should be integers and not strings

but no matter what I try I can seem to set a value and it does not show up under the root options block

And I'm assuming the custom column is a text field?

it is

And it's not expecting an integer and not a string either?

Its set as a freeform text so I would assume it does not matter?

OK

Okay, Ill give it a shot

Other than that, this is the code that I have for my test site that meets similar conditions to what your code is trying to do:

container.getComponent('Cart').addLine({
    line: {
        internalid: '3899',
        quantity: 1,
        item: {
            internalid: '3899'
        },
        options: [
            {cartOptionId: 'custcol1', value: {internalid: 'Test'}},
            {cartOptionId: 'custcol_gen_color', value: '3'},
            {cartOptionId: 'custcol_gen_size', value: '5'}
        ]
    }
})

Perhaps monkeying it to fit your site might work

But you think the syntax in general looks correct?

Apart from the arrow functions that we say you shouldn't use, yes 🙃

Great, thanks so much for the advice...

@Kirk Taylor I know Steve has mentioned in the past the quantity property type is number. I've had that issue before, trying to set quantity with a string and having inconsistent results.

I have changed it to integer.... Still no difference

Oh that's one thing that could be wrong but is present in my code example: you need to pass in an object as the value of the the option

Still no luck 😐 Ive set up custom fields 100 times but never with 2020+ and never tried to set with the extensibility api.

Oh yeah? How?

Well, I have done so much testing who knows what I jacked up so I realized I was testing with a transaction line field instead of a transaction line option field, so I recreated the correct field along with your passing the value as an object
