Hello,  
I’m trying to figure out how to get the pledge history for a member of a campaign. I’ve tried  
campaign = api\_client.get\_campaigns\_by\_id\_members(campaign\_id, page\_size=50, cursor=cursor,  
fields={‘member’: [  
‘pledge\_history’,  
]})  
and it returns that pledge\_history is not a valid field. The library doesn’t mention pledge\_history or pledge events, and I can’t figure out how to get them. I finally figured out how to get the pledge\_history of the user using a request, but I need the details from pledge event and don’t know what endpoint to get it from.

```
suffix = "campaigns/{}/members?include=pledge_history".format(campaign_id)
        response = requests.get(
            "https://www.patreon.com/api/oauth2/v2/{}".format(suffix),
            headers={
                'Authorization': "Bearer {}".format(access_token),
                'User-Agent': "Patreon CGT",
            }
        )
        campaign = response.json()

```

Please let me know what endpoint to use for this information

Hey NStephenH,

I’m running into the same issue. Were you able to solve for this?

That can be acquired by requesting pledge\_history as a relationship over member resource. When requesting the member resource, add pledge\_history as a relationship include in the request.

It’s been nearly a year, but here’s how I extract a pledge history. I think it was a formatting issue with my specific request.

> **Code**
>
> ```
> def get_pledge_history(self):
> access_token = self.creator_access_token
> api_client = patreon.API(access_token)
> campaign_id = api_client.get_campaigns(page_size=1).json_data['data'][0]['id']
> total_members = 1
> cursor = None
> members = []
> pledge_data = []
> while len(members) < total_members:
> suffix = "campaigns/{}/members?include=pledge_history&fields[pledge-event]=" \
> "date%2Ctype%2Cpayment_status%2Ctier_title&fields[member]=email".format(campaign_id)
> if cursor:
> suffix += ("&page[cursor]={}".format(cursor))
> response = requests.get(
> "https://www.patreon.com/api/oauth2/v2/{}".format(suffix),
> headers={
> 'Authorization': "Bearer {}".format(access_token),
> 'User-Agent': "Patreon CGT",
> }
> )
> 
> campaign = response.json()
> members += campaign['data']
> try:
> pledge_data += campaign['included']
> except KeyError:
> print("No members found")
> pagination = campaign['meta']['pagination']
> try:
> total_members = pagination['total']
> print("Downloading members {}/{}".format(len(members), total_members), end="\r", flush=True)
> cursor = pagination['cursors']['next']
> except KeyError as e:
> break
> 
> ```

Edit: Formatting

`pledge_history` is nice, and ~~it looks like it’s exactly the same as what we see when we click `See all payment history` for a particular member.~~

But am I correct in thinking that in `pledge_history`, there’s no way to tell whether the payment was for a month or a year? Is there any workaround to be able to differentiate between the length of a subscription?

My goal is to reconstruct the payment history.

**UPDATE:** There are major differences between what the website shows and the raw pledge history. It seems like the results are somehow non-trivially interpreted.

You should be able to match the pledge\_event to the tier, and from the tier you can deduce the cadence (year/month).

Isn’t cadence patron selectable?
