Update chart data in existing presentation (async)

Update supported bar or column chart data in an existing generated presentation while preserving all formatting.

Workflow:

PUT to this endpoint with your chart update data
Receive generation_id immediately (HTTP 202)
Poll GET /presentations/{generation_id}/status every 2-5 seconds
When status is completed, download from download_url

Accepts both ID formats:

gen_xxx - From slide/deck generation or chart updates
pres_xxx - Older direct-return generation output, if present

How it works:

Loads the existing presentation from storage
For each update, clones the target slide (preserving position) and updates chart data in-place
Saves as a new generated presentation

Important: Only provide data fields (categories, series, data_rows) in chart_data. Omit formatting fields (chart_type, title, legend, axes) to preserve existing formatting.

Authorizations

X-API-Key

string

header

required

Production API key. Development/test deployments may also allow X-Org-Name.

Path Parameters

presentation_id

string

required

Response

Chart update started - poll status endpoint for progress

Response schema for async generation requests.

This response is returned immediately when you POST to /presentations/generate or /presentations/generate-deck, and when you PUT to /presentations/{id}/update-charts. The actual Aspose work happens in the background.

Next steps:

Save the generation_id from this response
Poll status_url (or GET /presentations/{generation_id}/status) every few seconds
When status becomes completed, partial, or failed, generation is done
Download from download_url in the status response (for completed or partial)

generation_id

string

required

Unique identifier for this generation job. Use this to poll status and download the result.

Example:

"gen_abc123def456"

status

string

required

Initial status. Always 'pending' for new requests.

Example:

"pending"

status_url

string

required

Full URL to poll for generation status. Convenience field - you can also construct this as GET /presentations/{generation_id}/status.

Example:

"https://api.example.com/api/v1/presentations/gen_abc123def456/status"

created_at

string<date-time>

required

Timestamp when the generation request was created.

message

string

default:Generation started

Human-readable status message.

Example:

"Generation started. Poll status URL for progress."
