I want to print dynamic multiline text in whatsapp messages. The messages are sent via Facebook Graph API. I have used the \\n character to insert a new line. See request below.

Request:

POST https://graph.facebook.com/v20.0/XXXXXXXXXXXXXXXX/messages Content Type: application/json; charset=UTF-8 Body: {"messaging_product":"whatsapp","to":"XXXXXXXXXXX","type":"template","template":{"language":{"code":"en"},"name":"order_updated_message","components":[{"type":"body","parameters":[{"type":"text","text":"Jon Doe"},{"type":"text","text":2},{"type":"text","text":" *1. Wrapped Plate, 8 in | 1 Pc*\\nRate: 3.000\\nQty: 8000\\nAmount: 24000.00\\n\\n *2. Bottle Brush | 1 Pc*\\nRate: 18.644\\nQty: 11\\nAmount: 242.00"},{"type":"text","text":24242.00},{"type":"text","text":"John Lee"},{"type":"text","text":"+91XXXXXXXXX"}]}]}} 

The request succeeded till a few days ago, but then kept failing. See the failure response below.

Response:

HTTP Status: 400 Bad Request {     "error": {         "message": "(#100) Invalid parameter",         "type": "OAuthException",         "code": 100,         "error_data": {             "messaging_product": "whatsapp",             "details": "Param text cannot have new-line/tab characters or more than 4 consecutive spaces"         },         "fbtrace_id": "XXXXXXXXXXXXXXXXXXXX"     } } 

If I remove the \\n character, the request succeeds. So Im assuming the failure is caused by \\n itself.

I also tried replacing \\n with the following:

• \n --> same error
• \u000A --> same error
• %0A --> character displayed as it is. (No new-line)

Can you tell me what has gone wrong?

Note: The message body contains our customer's ordered items. The number of items can vary by order and hence the number of lines can vary in each message. Thus, I cannot add new lines in the message template.

I am trying to create an application that publishes posts to my Facebook Page. Here are the steps I have taken:

1. Create app via link https://developers.facebook.com/
2. In section Add use cases I selacted Other
3. Select an app type -> Buiseness
4. Then I created app
5. I didnt add any Add products to your app I directly go to https://developers.facebook.com/tools/explorer/
6. In permision section I selected pages_read_engagement and pages_manage_posts
7. Then in User or Pages I selected Get Page Access Token
8. I selected my page (I created it)
9. Then I generated access token
10. I run this query and copy number id from return
11. Then I run /id/feed POST to publish post:

I get error message that I'm not admin or have incorrect permissions. In my opinion this is correct so issue is somewhere other. Can you please help me find solution for running POST query and publish post on a FB page?

I'm currently working on a workflow to fetch all posts made by my company on social medias. On Facebook, I'm currently using the ads_posts endpoint to fetch both organic and paid posts (was previously using /feed for organic posts and /ads on the business account for paid posts, however the ads endpoint was lacking some posts that were created through dynamic ads).

The current request is like this:

https://graph.facebook.com/v21.0/{FB_PAGE_ID}/ads_posts?fields=id,created_time,updated_time&include_inline_create=true&access_token={PAGE_ACCESS_TOKEN}.  

The problem is, this endpoint only gets me data from within about a month ago. Any try to fetch data older than that using the filters "since" and "until" returns no data, and trying to go there manually through pagination gets me an error of:

Please reduce the amount of data you're asking for, then retry your request

(the "limit" filter doesn't help with this either).

Am I missing something here? Is this a limitation of the ads_posts endpoint? I couldn't find anything related to this on the API reference.

Also, i saw that the posts returned via /ads_posts are sorted by their creation time, while the ads fetched on the /ads are sorted by their update time. Is there any way to change the sorting of the ads_posts entries to their update time as well?

Thanks in advance!

Using https://graph.facebook.com/v21.0/{AD_ACCOUNT_ID}/ads?fields=id,created_time,updated_time,creative{effective_object_story_id}&access_token={USER_ACCESS_TOKEN} i'm able to get ads from 2024-12-01 and before, with their effective_object_story_id that I can access through the post endpoint and check that they in fact exist.

Using the mentioned /ads_posts request, it gets me only posts as old as from 2024-12-06 (3101 posts total). Anything older than this gets me an error or no data at all.

All the posts have been published the same way, and the tokens used have all the needed permission.

My client has an ad agency. I have to develop a comprehensive reporting of all the ads running currently, cost per lead and other details. I don't have much experience with Meta APIs, they have already given me full access to their entire business portfolio, ad accounts and pages.

The problem I am facing is that there does not seem to a straightforward way to achieve this. Even though I have full privileges, I am unable to figure it. This is what I have thought:

1. get Meta realtime updates through their webhooks.
2. call Meta API when necessary.

I am stuck on the first step. I am following the instructions on this page: https://developers.facebook.com/docs/graph-api/webhooks/getting-started It asked to do the following two things and I have done it

Create an endpoint on a secure server that can process HTTPS requests. Configure the Webhooks product in your app's App Dashboard. 

Now, to get the updates of Leads, I am following the instructions on the page: https://developers.facebook.com/docs/graph-api/webhooks/getting-started/webhooks-for-leadgen

It asks:

Install your app using your Facebook page 

these are the steps mentioned to install the app on Facebook page but the instructions are broken.

1. Select your app in the Application dropdown menu. This will return your app's access token.

2. Click the Get Token dropdown and select Get User Access Token, then choose the pages_manage_metadata permission. This will exchange your app token for a User access token with the pages_manage_metadata permission granted.

3. Click Get Token again and select your Page. This will exchange your User access token for a Page access token.

4. Change the operation method by clicking the GET dropdown menu and selecting POST.

5. Replace the default me?fields=id,name query with the Page's id followed by /subscribed_apps?subscribed_fields=leadgen, then submit the query.

6. Select your app in the Application dropdown menu. This will return your app's access token. IT doesn't..

7. in step 2, the moment I select User access Token, a popup opens which asks to reconnect the app. there is no time to choose pages_manage_metadata. cannot move beyond this. I have already tried several things out of frustration, searched on google, ask ChatGPT and Gemini. Nothing seem to work.

I don't understand why this is so difficult and confusing when I have the full rights and doing it just for myself. If I had this public app on which multiple people were able to connect, but just for an in-house things, it seems unnecessarily complicated.

if anyone can, please help.

I created a sandbox ad account on Facebook API then created a system user, put all the permissions on it and associated it with this sandbox ad account to be able to create the ads but when I try to create an ad it asks to add a payment method.

How can I add a payment method to an account that should be a test account?

How do I resolve this?
