Update table content using API

[Tomasz Cyranski]

I want to update Absences column via API for confluence page like this:


My aim is fetch data regarding timeoffs and put it here on confluence page. Is there any elegant way to do it? 
I managed to fetch data from Clockify already and it looks like json below:
[
{
"userName": "Client dev 1",
"timeOffPeriods": [
{
"start": "2025-08-15",
"end": "2025-08-15"
},
{
"start": "2025-09-15",
"end": "2025-09-19"
},
{
"start": "2025-09-22",
"end": "2025-09-22"
},
{
"start": "2025-12-22",
"end": "2025-12-23"
},
{
"start": "2025-12-24",
"end": "2025-12-26"
},
{
"start": "2025-12-29",
"end": "2025-12-31"
},
{
"start": "2026-01-01",
"end": "2026-01-01"
}
]
},
{
"userName": "Client dev 2",
"timeOffPeriods": [
{
"start": "2025-08-11",
"end": "2025-08-15"
},
{
"start": "2025-09-15",
"end": "2025-09-19"
}
]
},
{
"userName": "Client dev 3",
"timeOffPeriods": [
{
"start": "2025-08-25",
"end": "2025-08-25"
}
]
}
]

Hi @Tomasz Cyranski ,

You can't update Confluence tables with API access.  It's unfortunately only manual.

[Tomasz Cyranski]

ok so is there any way to do it via API?
Like:
1. GET all page 
2. parse it outside
3 make needed changes
4. PUT whole page 

IS there any examples of it? Anyone tried that approach?

This should be possible, however I have no examples.
